Best Receiver Hitch For RV: Compare Frame and Bumper Mounts

Best Receiver Hitch For RV

A strong RV receiver hitch should match your mounting point and intended load, whether you need a frame-mounted hitch for towing or a bumper receiver for accessories. The CURT 13703 leads this group with a 2-inch receiver, adjustable fit for compatible RV frames up to 72 inches, and ratings of 3,500 pounds gross trailer weight and 350 pounds tongue weight. Those ratings are subject to the lowest-rated component, RV frame capacity, and vehicle limits.

Several bumper-mounted options instead provide a receiver for bike racks or cargo carriers and explicitly warn against trailer towing. Check your bumper dimensions or frame layout before choosing: a receiver’s opening size alone does not confirm that it fits your RV or can handle your planned load.

This roundup separates those use cases and highlights their stated limits.

The CURT 13703 Adjustable RV Trailer Hitch is the best overall choice for compatible RV frames when you need a versatile 2-inch receiver and stated towing capacity. It is rated for 3,500 pounds gross trailer weight and 350 pounds tongue weight, with a maximum 72-inch fit. Those limits remain subject to the lowest-rated towing component, RV frame capacity, and vehicle manufacturer limits.

For a bumper-mounted accessory receiver rather than towing, choose an option matched to your bumper dimensions instead.

Detailed Reviews: Best Receiver Hitch For RV

CURT 13703 Hitch

#1 · Best Overall

1. CURT 13703 Hitch

  • Material: Carbon Steel
  • Compatible with Vehicle Type: ATV, Marine-Personal-Craft, Trailer

Best for: Adjustable frame-mounted towing.

Why it ranks #1: Its adjustable frame-mounted design fits up to 72 inches and provides a 2-inch receiver rated at 3,500 pounds gross trailer weight and 350 pounds tongue weight.

A 72-inch maximum width gives the CURT 13703 an adjustable span for compatible RV, camper, and motorhome frames. Its 2-inch receiver can serve towing or accessory needs, while the stated 3,500-pound gross trailer weight and 350-pound tongue weight ratings provide specific capacity limits to consider alongside the RV frame and other towing components.

The adjustable design and standard 2-by-2-inch receiver let compatible RV frames accept cargo carriers, towing accessories, trailers, or a small vehicle for flat towing. Its 3,500-pound gross trailer weight and 350-pound tongue weight ratings apply only within the limits of the lowest-rated towing component, RV frame, and vehicle manufacturer. At 98.5 pounds, this hitch is a substantial component to account for during handling and installation.

Pros
  • Adjustable design reaches a maximum width of 72 inches
  • Standard 2-by-2-inch receiver
  • Rated for 3,500 pounds gross trailer weight and 350 pounds tongue weight
  • Supports listed uses including cargo carriers, trailers, and flat towing a small vehicle
Cons
  • At 98.5 pounds, the hitch is a substantial component to handle during installation.

Skip it if you need a lightweight bumper adapter for accessories; the 98.5-pound CURT frame hitch is a substantial installation component.

This CURT suits RV owners seeking an adjustable frame-mounted receiver for towing or accessories, including flat-towing a small vehicle. Check the frame and every towing component against the stated ratings; the hitch's maximum width is 72 inches.

ALMULOO Adjustable Hitch

#2 · Adjustable Frame Fit

2. ALMULOO Adjustable Hitch

  • Maximum Towing Capacity: 3500 lb
  • Material: Alloy Steel
  • Compatible with Vehicle Type: RV

Best for: Adjustable frame hitch for accessories.

Why it ranks #2: This three-piece frame hitch is rated for 3,500 pounds trailer weight and 350 pounds tongue weight, and its stated frame fit extends up to 7 inches.

A three-piece adjustable design that fits frames up to 76 inches makes the ALMULOO hitch useful when a fixed-width frame receiver is not the right match. Its 2-inch receiver accepts ball mounts, cargo racks, and bike racks, and its stated ratings are 3,500 pounds trailer weight and 350 pounds tongue weight.

Direct bolt-on installation avoids a welding step, while the three-piece adjustable layout accommodates frames up to 76 inches, according to the supplied features. The 2-inch receiver accepts common listed accessories such as ball mounts and cargo racks, but the product specifically excludes vertical hanging bike racks. Its 3,500-pound trailer-weight and 350-pound tongue-weight ratings give buyers limits to compare with their RV frame and the rest of the towing setup.

Pros
  • Three-piece adjustable design fits frames up to 76 inches
  • Direct bolt-on installation
  • 2-inch receiver accepts ball mounts and cargo racks
  • Rated for 3,500 pounds trailer weight and 350 pounds tongue weight
Cons
  • Does not support vertical hanging bike racks.

Skip it if you need to carry vertical hanging bikes; the ALMULOO hitch specifically does not support that rack style.

This ALMULOO is for RV owners who want an adjustable, direct-bolt-on frame hitch for listed accessories or towing. Check frame width against the 76-inch maximum, and choose another setup for vertical hanging bike racks.

KUAFU Universal Hitch

#3 · Broad Accessory Use

3. KUAFU Universal Hitch

  • Maximum Towing Capacity: 3500 lb
  • Compatible with Vehicle Type: Trailer

Best for: Frame receiver for towing accessories.

Why it ranks #3: Its 2-inch Class 3 receiver is rated for 3,500 pounds gross trailer weight and 350 pounds tongue weight, with listed uses including ball mounts and carriers.

A 2-inch Class 3 receiver rated for 3,500 pounds gross trailer weight gives the KUAFU hitch a clear role for compatible frame-mounted towing and accessory setups. It also lists a 350-pound tongue-weight capacity and accommodates ball mounts, cargo carriers, bicycle frames, trailers, and winches among other heavy accessories.

The included hardware fastens the receiver to the frame, avoiding a need to source the listed attachment hardware separately. Its 2-inch opening accepts a range of named mounts and accessories, from ball mounts and cargo carriers to bicycle frames and winches. Heavy-duty steel and a black powder-coated finish are specified, while the 3,500-pound gross trailer weight and 350-pound tongue weight ratings set limits to check against the frame and other components.

Pros
  • 2-inch Class 3 receiver
  • Rated for 3,500 pounds gross trailer weight and 350 pounds tongue weight
  • Includes frame-fastening hardware
  • Black powder-coated heavy-duty steel construction
Cons
  • The supplied details do not specify an adjustable-width frame range.

Skip it if you need a listed adjustable frame-width range; CURT's 13703 gives a maximum width of 72 inches.

KUAFU fits buyers seeking a frame-fastened 2-inch receiver for listed towing accessories, with hardware included and explicit capacity ratings. Consider frame compatibility carefully; the supplied details do not give an adjustable-width range.

Stromberg Carlson CC-300

#4 · Frame Accessory Mount

4. Stromberg Carlson CC-300

  • Material: Alloy Steel
  • Compatible with Vehicle Type: Car, Trailer

Best for: Adjustable fifth-wheel accessory hitch.

Why it ranks #4: This adjustable accessory hitch creates a 2-inch receiver on trailers and fifth wheels, with bolt-on Class I or welded Class II installation options.

The Stromberg Carlson CC-300 creates a 2-inch hitch on travel trailers and fifth wheels, with a choice of bolting it on as Class I or welding it on as Class II. That installation choice makes it relevant to buyers planning a frame-mounted receiver specifically for bike racks and cargo carriers.

The CC-300's adjustable accessory-hitch format supplies a 2-inch receiver for bike racks and cargo carriers at the back of a camper, travel trailer, or fifth wheel. Bolting it on as Class I or welding it on as Class II gives two listed attachment approaches, so installation preference matters when choosing. Its supplied details do not list towing or tongue-weight capacities, making it important to keep the stated accessory use distinct from choosing a rated trailer-towing hitch.

Pros
  • Creates a 2-inch hitch on travel trailers and fifth wheels
  • Can be bolted on as Class I
  • Can be welded on as Class II
  • Intended for bike racks and cargo carriers
Cons
  • No towing or tongue-weight capacity is listed in the supplied details.

Skip it if you need a listed towing capacity; CURT's 13703 specifies gross trailer and tongue-weight ratings.

Pick the CC-300 if you need an adjustable 2-inch accessory hitch for a camper, travel trailer, or fifth wheel and can choose between bolting and welding. Its supplied details do not establish towing capacity.

METOWARE Bumper Hitch

#5 · Higher Tongue Rating

5. METOWARE Bumper Hitch

  • Maximum Towing Capacity: 3500 lb
  • Material: Alloy Steel
  • Compatible with Vehicle Type: Car, RV, Truck

Best for: Four-inch bumper towing receiver.

Why it ranks #5: For a 4-inch square bumper, it provides a 2-inch receiver and 350-pound tongue rating; its listed 3,500-pound capacity does not establish RV-frame suitability.

A 3,500-pound maximum towing capacity makes the METOWARE receiver an option for buyers considering more than a rack mount on a 4-inch square RV bumper. Its 350-pound tongue-weight capacity and standard 2-inch receiver also accommodate listed hitch accessories, including bike racks and ball mounts, within the limits of the complete towing setup.

The 2-inch receiver is compatible with most Class III and IV ball mounts, bike racks, and cargo accessories, letting buyers use common shanks and mounts. Its stated 3,500-pound towing and 350-pound tongue-weight capacities clarify the receiver's listed limits, while high-strength alloy steel provides the specified construction. The title identifies a 4-inch square bumper fit, so buyers can compare that bumper dimension with their RV before choosing this adapter.

Pros
  • Fits a 4-inch square bumper
  • Standard 2-inch receiver works with most Class III and IV ball mounts
  • Rated for 3,500 pounds maximum towing capacity
  • 350-pound tongue-weight capacity
Cons
  • The supplied product details do not specify installation hardware.

Skip it if you need an included hitch pin and cover; the Ohuhu RV Bumper Hitch lists both components.

Consider METOWARE if your RV has a 4-inch square bumper and you want a receiver with stated towing and tongue-weight capacities plus compatibility with common mounts. Keep the complete setup's limits in mind.

TOPTOW Bumper Receiver

#6

6. TOPTOW Bumper Receiver

  • Maximum Towing Capacity: 3500 lb
  • Material: Alloy Steel
  • Compatible with Vehicle Type: 4" X 4" RV REAR BUMPER

Best for: Four-inch bumper accessory mount.

Why it ranks #6: This receiver fits 4-by-4-inch bumpers and has a 350-pound tongue rating, but the listing cautions that it is not intended for RV trailer towing.

A receiver that can mount upside down gives the TOPTOW bumper hitch an extra installation orientation for compatible 4-by-4-inch square bumpers. Its 2-inch opening accepts many bike racks and cargo carriers, while the stated 350-pound tongue-weight capacity helps define its accessory-carrying limit. TOPTOW specifically warns that this receiver is not for RV-level trailer towing.

The bolt-on design secures around a 4-by-4-inch bumper, and the instructions emphasize tightening the bolts securely. The ability to mount upside down adds an orientation choice without changing the listed bumper size. A 2-inch receiver fits many bike racks and cargo carriers with matching shanks, while the 350-pound tongue-weight capacity is relevant when loading accessories. A 5/8-inch hitch pin or lock is not included, so plan for that separately.

Pros
  • Fits 4-by-4-inch square RV bumpers
  • Can be mounted upside down
  • 2-inch receiver accepts many accessories with 2-inch shanks
  • 350-pound tongue-weight capacity is specified
Cons
  • A 5/8-inch hitch pin or hitch lock is not included.

Skip it if you need a receiver for RV-level trailer towing; TOPTOW explicitly excludes that use.

Pick this TOPTOW for accessory mounting on a 4-by-4-inch bumper when upside-down installation is useful. Its 350-pound tongue-weight rating and explicit no-trailer-towing warning make the intended boundary important to observe.

Fioracl Adjustable Receiver

#7

7. Fioracl Adjustable Receiver

  • Maximum Towing Capacity: 3500 lb
  • Material: Alloy Steel
  • Compatible with Vehicle Type: Trailer

Best for: Adjustable-width bumper accessory mount.

Why it ranks #7: Its adjustable design is stated to accommodate steel beams from 2.5 to 4 inches and offers a 2-inch opening for accessories; capacity details need careful verification.

An adjustable clamp that accommodates different steel-beam widths and heights is the defining feature of this Fioracl bumper receiver. It is intended to lock tightly around the beam to reduce movement, while the 2-inch opening fits many bike racks, cargo carriers, hitch steps, and RV tire racks with matching shanks.

Unlike a receiver specified for one bumper dimension, this model's adjustable design is described as accommodating different beam widths and heights. That gives buyers more flexibility when matching a steel bumper beam, with the clamp intended to hold it securely and limit shaking. The 2-by-2-inch receiver takes many listed accessories, including bike racks and cargo carriers. The product details also state a 3,500-pound maximum towing capacity; check the intended application and full setup limits.

Pros
  • Adjusts for different steel-beam widths and heights
  • Clamping design is intended to limit movement
  • 2-by-2-inch receiver accepts many listed accessories
  • 3,500-pound maximum towing capacity is specified
Cons
  • The supplied details do not state a tongue-weight capacity.

Skip it if you require a stated tongue-weight limit; Nilight's 92116B lists a 200-pound tongue-weight capacity.

Choose Fioracl if your bumper beam's width or height calls for an adjustable clamp and you need a 2-inch accessory receiver. Its stated towing capacity does not provide a tongue-weight figure, so account for that limitation.

Ohuhu Bumper Hitch

#8

8. Ohuhu Bumper Hitch

  • Maximum Towing Capacity: 3500 lb
  • Material: Alloy Steel
  • Compatible with Vehicle Type: Trailer

Best for: Bumper receiver with pin and cover.

Why it ranks #8: Designed for a 4-by-4-inch RV bumper, it includes a hitch pin and cover and is intended for racks and other accessories rather than confirmed towing.

A hitch pin and receiver cover are included with the Ohuhu bumper hitch, so the basic receiver setup comes with both a securing component and a cap for unused times. It fits 4-by-4-inch RV or travel-trailer bumpers and provides a 2-inch opening for listed accessories such as bike and cargo racks.

Installation does not require welding: the receiver attaches to the bumper for mounting compatible racks and other accessories. The included hitch pin supports securing the mounted accessory, while the hitch cover caps the receiver when it is not in use. Its E-coat and black powder-coat finish is specified to help resist rust and corrosion. The 4-by-4-inch bumper fit is a key boundary, and the supplied details list a 3,500-pound maximum towing capacity.

Pros
  • Fits 4-by-4-inch RV or travel-trailer bumpers
  • Includes a hitch pin and receiver cover
  • Installation does not require welding
  • E-coat and powder coating are specified to resist rust and corrosion
Cons
  • The supplied product details do not state a tongue-weight capacity.

Skip it if you need a stated tongue-weight capacity; Nilight's 92116B specifies 200 pounds for that rating.

This Ohuhu suits owners with a 4-by-4-inch bumper who value an included pin and cover for accessory use. Its coating supports corrosion resistance, but the supplied details do not give a tongue-weight rating.

Nilight Bumper Hitch

#9

9. Nilight Bumper Hitch

  • Material: Alloy Steel, Carbon Steel
  • Compatible with Vehicle Type: Trailer

Best for: Two-inch bumper accessory receiver.

Why it ranks #9: Its 2-inch receiver fits 4-to-4.5-inch beams and is rated at 2,000 pounds gross trailer weight and 200 pounds tongue weight, subject to the lowest-rated component.

A 2-inch receiver opening lets this Nilight bumper hitch accept many bike racks and cargo carriers with matching shanks. It fits beams from 4 to 4.5 inches and uses a bolt-on design, giving buyers a defined bumper range to check before installation. The stated limits are 2,000 pounds gross trailer weight and 200 pounds tongue weight.

The bolt-on steel receiver is specified for 4-to-4.5-inch beams, which gives its fit a narrower, explicit range than a generic bumper mount. Its 2-by-2-inch opening accommodates many racks and carriers with 2-inch shanks, while the 200-pound tongue-weight limit informs accessory loading. The listed 2,000-pound gross trailer weight is subject to the lowest-rated towing component, so it should not be treated as the only limit in a towing setup.

Pros
  • Fits beams measuring 4 to 4.5 inches
  • Bolt-on installation
  • 2-by-2-inch opening fits many accessories with 2-inch shanks
  • Rated for 2,000 pounds gross trailer weight and 200 pounds tongue weight
Cons
  • The 200-pound tongue-weight rating is lower than the 350-pound rating of some listed options.

Skip it if you need a 350-pound tongue-weight rating; TOPTOW's TTRV801 lists that capacity for accessory use.

This Nilight suits buyers with a 4-to-4.5-inch bumper beam who want a bolt-on receiver for compatible racks or carriers. Its 200-pound tongue-weight and 2,000-pound gross-trailer-weight ratings define the limits to assess.

MaxxHaul 50173 Adapter

#10

10. MaxxHaul 50173 Adapter

  • Material: Alloy Steel
  • Compatible with Vehicle Type: RV

Best for: Four-inch bumper accessory adapter.

Why it ranks #10: This adapter fits 4-inch square RV bumpers and provides a 2-inch receiver with 200-pound tongue capacity, but explicitly is not for trailer towing.

A 2-inch receiver for a 4-inch square RV bumper gives this MaxxHaul adapter a focused job: adding a mounting point for compatible hitch accessories. Its 200-pound tongue-weight capacity and all-steel construction suit buyers who want to add options such as a bike rack or RV tire carrier without a separate frame hitch.

The 2-by-2-inch opening accepts accessories with a 2-inch shank, including bike racks, RV tire carriers, and hitch steps, so one receiver can serve several accessory needs. Its specified fit is a 4-inch square bumper, making bumper dimensions the key installation consideration. The 200-pound tongue-weight limit sets a clear boundary for loaded accessories. MaxxHaul explicitly says this adapter is not for RV-level trailer towing; cargo-carrier use also calls for caution.

Pros
  • Adds a 2-by-2-inch receiver to a 4-inch square RV bumper
  • Accepts accessories with 2-inch shanks
  • 200-pound tongue-weight capacity is stated
  • All-steel construction is described as durable and rust resistant
Cons
  • Not intended for RV-level trailer towing, and cargo-carrier use requires caution.

Skip it if you need a receiver for trailer towing; this adapter is explicitly not intended for that purpose.

Choose this MaxxHaul adapter if your RV has a 4-inch square bumper and you need a receiver for compatible accessories such as a bike rack or tire carrier. Keep its 200-pound tongue-weight limit and towing restriction in view.

Why bumper receivers can be a towing trap

A bumper receiver’s stated capacity does not by itself mean it is suitable for towing a trailer. Several listings draw that distinction directly: MaxxHaul says its 200-pound tongue-capacity adapter is not meant for RV-level trailer towing, and TOPTOW likewise warns against that use. By contrast, frame-mounted options such as CURT 13703 state a gross trailer weight and tongue weight rating while also limiting use to the lowest-rated component, the RV frame capacity, and vehicle-manufacturer limits.

Do not treat a receiver’s advertised maximum towing capacity as proof that your bumper, frame, or complete towing setup can handle that load. Identify where the hitch attaches, check the RV and hitch instructions, and use the lowest applicable rating.

For bike racks and cargo carriers, also confirm the accessory’s load and whether its manufacturer permits use on your RV.

Measure the mounting point before choosing a receiver

The key fit trap is matching only the receiver opening while overlooking the RV-side mounting dimensions. These products include bumper receivers for 4-inch square beams, a TOPTOW model for 4-by-4-inch bumpers, and a Nilight option stated to fit beams from 4 to 4.5 inches. Fioracl instead describes an adjustable range of 2.5 to 4 inches.

Those dimensions refer to the beam or bumper fit, not the standard 2-inch accessory opening. Frame-mounted designs solve a different problem: CURT lists a maximum 72-inch fit, while ALMULOO describes an adjustable design for frames up to 7 inches.

Before ordering, measure the bumper or frame where the hitch will attach and compare that measurement with the product’s actual fit description. Also check for clearance around the mounting area; the provided listings do not establish clearance for every RV layout.

How to Choose an RV Receiver Hitch

Mounting location and fit

Choose a hitch whose stated fit matches the RV’s frame or bumper, not just the accessory’s 2-inch shank. Bumper choices vary: MaxxHaul specifies a 4-inch square bumper, TOPTOW a 4-by-4-inch bumper, Nilight a 4-to-4.5-inch beam, and Fioracl an adjustable beam range of 2.5 to 4 inches. For frame mounting, CURT lists compatibility up to 72 inches, while ALMULOO describes fit for frames up to 7 inches.

A bumper-mounted option suits a buyer adding a rack to a compatible bumper; a frame-mounted model is the more relevant starting point for towing. Measure the attachment point and confirm the product’s mounting instructions before choosing.

Load rating and intended use

Match the stated ratings to your intended load, and distinguish trailer towing from carrying accessories. CURT, ALMULOO, and KUAFU list 3,500-pound gross trailer weight and 350-pound tongue weight ratings, while Nilight lists 2,000 and 200 pounds respectively. MaxxHaul lists a 200-pound tongue capacity and explicitly excludes RV-level trailer towing; TOPTOW also cautions against trailer towing despite its listed 350-pound tongue rating.

A frame-hitch buyer seeking stated towing ratings should compare the first group, while a buyer mounting a bike rack should check accessory and RV limits instead. In every case, the applicable limit is no greater than the lowest-rated component or RV/vehicle limit.

Adjustability and installation details

Look for an installation style and adjustment range that suit your RV’s mounting point. CURT is adjustable and lists a maximum 72-inch fit; ALMULOO uses a three-piece adjustable design and describes frame fit up to 7 inches. Stromberg Carlson offers an accessory hitch that can be bolted on as Class I or welded on as Class II.

Bumper options vary too: Fioracl adjusts for different beam widths and heights, while Ohuhu describes installation without welding and includes a hitch pin and cover. A buyer with a compatible frame and variable spacing may prefer an adjustable frame hitch; someone with a matching bumper and a rack-only need may prefer a bumper receiver.

Verify the required hardware and installation method for your specific RV.

Which RV receiver hitch should I choose?

Choose the CURT 13703 Hitch if you need a frame-mounted 2-inch receiver with stated towing ratings and your RV frame fits its listed 72-inch maximum. The ALMULOO Adjustable Hitch and KUAFU Universal Hitch are alternatives with listed 3,500-pound gross trailer weight and 350-pound tongue weight ratings; check their fit and installation details before selecting one. For a frame-mounted accessory receiver on a trailer or fifth wheel, consider the Stromberg Carlson CC-300.

If you only need a bumper receiver for a bike rack or carrier, match the bumper dimensions: METOWARE Bumper Hitch fits a 4-inch square bumper, while Nilight Bumper Hitch is listed for 4-to-4.5-inch beams. Do not use a bumper accessory receiver for trailer towing unless the product and RV manufacturers explicitly approve that use.

Frequently Asked Questions

How can I tell whether my RV bumper is strong enough for a hitch-mounted rack?

Check the RV and bumper documentation for an approved load and confirm the bumper’s size and construction match the receiver’s stated fit. A receiver’s own capacity does not establish the bumper’s capacity. If documentation does not confirm suitability for the rack and its load, ask the RV manufacturer or a qualified installer before mounting it.

Can an RV bumper receiver tow a trailer, or is it only for accessories?

Treat a bumper receiver as an accessory mount unless both the receiver and RV manufacturers explicitly approve it for trailer towing. The editorial guidance identifies bumper-mounted options for racks and carriers, not towing. For towing, consider a frame-mounted hitch with stated ratings, and follow the lowest-rated component, RV frame capacity, and vehicle manufacturer limits.

How do I determine whether a frame-mounted hitch will clear my RV body and components?

Compare the hitch’s listed fit dimensions with the RV frame, then check the intended mounting position against the body and nearby components. The CURT 13703 lists a maximum 72-inch fit, but that does not confirm clearance on every RV. Have fit and installation details checked before selecting or installing a frame-mounted hitch.

What should I measure before choosing a bumper-mounted receiver?

Measure the bumper’s shape and dimensions, then compare them with the receiver’s stated fit. For example, the METOWARE option is identified for a 4-inch square bumper, while Nilight is listed for 4-to-4.5-inch beams. Confirm the exact fit and intended accessory use rather than relying on a similar-looking bumper.

How should I compare towing ratings between frame-mounted hitch options?

Compare each hitch’s stated gross trailer weight and tongue weight ratings, then verify the RV frame and vehicle limits. The CURT 13703, ALMULOO Adjustable Hitch, and KUAFU Universal Hitch are listed at 3,500 pounds gross trailer weight and 350 pounds tongue weight. The usable limit remains the lowest applicable rating.

Final Words

For towing, start with the CURT 13703 if your RV frame fits its listed 72-inch maximum, and verify that the frame, vehicle, and every towing component support the load. ALMULOO and KUAFU are alternatives with listed 3,500-pound gross trailer weight and 350-pound tongue weight ratings; check their fit and installation details. For accessories, match a bumper receiver to your bumper dimensions, or consider the Stromberg Carlson CC-300 for a frame-mounted accessory receiver.

Do not assume an accessory receiver is approved for towing.
