Best Generator Tray For Trailer: Compare A-Frame and Slide-Outs

#1 · Best Overall

1. Stromberg Carlson CC-255

• Weight: 62 lb

Best for: A-frame generator haulers.

Why it ranks #1: Its A-frame mount directly suits a trailer tongue, and the listed 300-pound capacity and 35.98-by-24.02-inch dimensions give buyers concrete fit checks.

A 300-pound capacity gives the Stromberg Carlson CC-255 room for a generator alongside other bulky travel gear. Its A-frame mount places cargo over the trailer’s softer-riding area, helping RVers carry equipment up front while keeping more interior storage available for the trip.

The tray measures 35.98 by 24.02 inches, providing a broad platform for generators, coolers, bikes, or tools. Its A-frame mounting position uses trailer tongue space and keeps gear accessible outside the living area. The listed 300-pound capacity gives a clear upper limit for planning a load, while the 62-pound tray weight is worth factoring into handling and the trailer’s overall tongue load. This is a cargo platform, not an enclosed carrier.

Skip it if you need a pull-out compartment tray; the RecPro Generator Slide Out Tray provides sliding access to a generator stored behind a baggage door.

Choose this for an RV owner who wants a broad, front-mounted platform for a generator or mixed travel cargo. Its 300-pound limit and 62-pound tray weight both matter when planning the A-frame load.

#2 · Adjustable A-Frame

2. Stromberg Carlson CC255

• Weight: 68 lb

Best for: Adjustable A-frame carriers.

Why it ranks #2: The listing describes an adjustable tongue cargo system that fits most A-frame trailers, making it closely matched to exterior trailer generator transport.

An adjustable fit for most A-frame trailers makes the Stromberg Carlson CC255 a flexible tongue-cargo option, enabling owners with different trailer setups to carry gear outside the living space. Its 36-by-24-inch platform gives generators and other cargo a broad, simple tray surface.

The listed dimensions are 36 by 24 by 5 inches, so buyers can compare the platform’s footprint with the gear they want to carry. Its adjustable design is described as fitting most A-frame trailers, while the listing advises checking vehicle compatibility for fitment. At 68 pounds, the tray itself is a substantial item to position and adds weight before cargo is loaded. The supplied information does not state a cargo capacity.

Skip it if you want a published cargo limit for a heavy load; the Stromberg Carlson CC-255 listing specifies capacity up to 300 pounds.

Consider this for an A-frame trailer owner seeking an adjustable, broad tongue tray for equipment. Its 68-pound weight and the need to check vehicle fitment are important boundaries before selecting it.

#3 · Adjustable Storage

3. KUQAE A-Frame Tray

• Weight: 40 lb

Best for: Adjustable tongue cargo users.

Why it ranks #3: This A-frame tray is intended for generator storage and offers adjustable height and width, though the listing does not state a load capacity.

Adjustable height and width let the KUQAE tray reconfigure around gear of different sizes, enabling RV owners to organize generators, coolers, bikes, or spare tires on an A-frame-mounted platform. That flexibility suits changing cargo needs rather than a single fixed-size loadout.

The listing describes the tray as an A-frame mount and names storage uses ranging from generators and camping gear to tools and spare tires. Height and width adjustment let owners change the layout for differently sized equipment, which can make loading a mixed set of supplies more manageable. At 40 pounds, the tray’s own weight is also a factor when handling it or accounting for added trailer load. The supplied details do not give a cargo capacity.

Skip it if you need a stated load limit before loading a heavy generator; the Stromberg Carlson CC-255 specifies a 300-pound capacity.

This suits an RV owner who values adjustable dimensions for varied outdoor gear on an A-frame tray. Consider it when flexibility matters, but the supplied product details leave the allowable cargo load unspecified.

#4 · Tongue Fit Flexibility

4. LWHwareHT Tongue Rack

Best for: Adjustable trailer-tongue rack buyers.

Why it ranks #4: Its three adjustable brackets are described as fitting most A-frame RV trailers, with the listing also noting compatibility with a trailer tongue jack.

Three adjustable brackets let the LWHwareHT rack adapt to trailer-tongue size and turning radius, enabling use across different A-frame setups. The tongue-mounted platform is intended for generators, coolers, and compressors, making it a way to use front-end space for outdoor cargo.

The listing describes the three brackets as adjustable to the trailer tongue and turning radius, and says the rack is compatible with a trailer tongue jack. That adjustment can help owners arrange the rack around front-end hardware while using tongue space for cargo. Generators, coolers, and compressors are named as intended loads. The supplied details do not state platform dimensions or a cargo capacity, so those specifics are not available for matching equipment or setting a load limit.

Skip it if you need a stated load limit for a heavy generator; the Stromberg Carlson CC-255 specifies capacity up to 300 pounds.

Consider this for an A-frame trailer owner who wants adjustable tongue storage for a generator or cooler and needs jack compatibility. The listed details do not provide dimensions or a cargo rating.

#5 · Rear-Bumper Mount

5. Keliejnese Bumper Carrier

Best for: Four-inch bumper cargo carriers.

Why it ranks #5: This exterior carrier is made for 4–4.5-inch RV or trailer bumpers and includes a cargo net, but it requires a compatible rear bumper.

A mounting system specified for 4–4.5-inch RV or trailer bumpers makes this Keliejnese carrier a rear-mounted alternative to a tongue tray, enabling cargo transport at the back of a trailer. Its textured surface and included cargo net help restrain shifting items.

Pre-drilled holes and included hardware are listed to support tool-free installation, while the bumper-size specification gives buyers a concrete compatibility range to check. The textured surface and included optional cargo net address cargo movement, and reflective stickers add visibility at night. Alloy-steel construction forms the carrier material. This setup uses the rear bumper rather than an A-frame, so bumper compatibility and rear clearance are central fit considerations for an RV or trailer.

Skip it if you need an A-frame-mounted carrier rather than a rear bumper rack; the LWHwareHT trailer tongue tray uses adjustable brackets.

This suits an RV owner with a compatible rear bumper who wants a carrier with cargo-restraint features and reflective stickers. Its stated bumper range and rear-mounted position are the key fit boundaries.

#6

6. Mount-n-Lock GennyGo RevX

Best for: Modular aluminum tray-pan owners.

Why it ranks #6: Its aluminum tray pan has more than 60 edge tie-down points and can be combined with support arms, but the listed item is the pan only.

More than 70 listed tie-down points give the Mount-n-Lock GennyGo RevX pan multiple places to secure cargo, enabling flexible restraint for equipment on an aluminum platform. Its pan-only configuration is essential to note: complete installation requires compatible RevX support arms.

The aluminum tray pan provides tie-down points around its edge and across its center, giving users several cargo-securing positions. Three assembly options are included, and additional trays can be added to build a platform up to eight feet wide, supporting modular layouts. The pan weighs eight pounds according to the additional product description. However, this listing is for the tray pan only; RevX cargo box support arms are required to make a complete tray kit, so plan for that component separately.

Skip it if you want a complete slide-out generator tray rather than a modular pan; the RecPro Generator Slide Out Tray provides compartment access.

Choose this for a buyer assembling a modular cargo platform who values multiple tie-down positions and expansion options. It is not a complete tray kit on its own; compatible RevX support arms are required.

#7

7. RecPro Generator Slide-Out

Best for: Baggage-compartment generator access.

Why it ranks #7: This generator-specific slide-out uses 12-gauge steel and positive locking latches, but mounts under an RV compartment rather than on a trailer tongue.

Positive-locking latches secure the RecPro tray during transit, while its slide-out format brings a generator stored behind an RV baggage door within reach. That pairing enables more convenient access to a compartment-stored generator without lifting it out for every use.

RecPro describes this as a generator slide-out tray that mounts under RV compartment and baggage doors, specifically providing access to a generator stored in a baggage compartment. The positive-locking latches help keep the generator secure while the RV is in transit, and friction straps are included as additional listed components. Its 12-gauge steel construction provides a specified material, but the listing does not provide a tray load capacity or platform dimensions for comparison.

Skip it if you need a listed platform size and load rating to plan a larger installation; the QTSZNDF slide tray specifies dimensions and a 264-pound capacity.

This is a fit for an RV owner storing a generator behind a baggage door who wants slide-out access and locking latches for travel. The generator must be supplied separately, and the listing gives no capacity figure.

#8

8. QTSZNDF Generator Slide-Out

• Weight: 22 lb

Best for: Compact high-capacity slide users.

Why it ranks #8: Its 22.6-by-13-inch platform supports up to 264 pounds and has full-extension rails, but it is designed for an RV storage compartment.

A 264-pound capacity on a 22.6-by-13-inch platform gives the QTSZNDF slide tray a substantial stated load limit in a compact footprint, enabling pull-out access to generators, batteries, or toolboxes in an RV compartment.

Full-extension ball-bearing rails bring equipment toward the user, reducing the need to reach deep into a storage compartment to access a generator or battery. A built-in locking mechanism helps keep the loaded tray stable during travel, and the stated 264-pound capacity gives a defined limit for load planning. The 22.6-by-13-by-2-inch platform is relatively compact, so its usable area should be checked against the gear’s footprint before installation.

Skip it if you need a 24-inch-square platform; the ONLYLIDA 24-by-24-inch steel slide tray offers a wider listed footprint.

This suits an RV owner who wants a defined load limit and pull-out access in a compact compartment. The 13-inch width is the main boundary, so check whether the equipment base fits the platform.

#9

9. YANZLAROX Sliding Tray

• Weight: 31.5 lb

Best for: Heavy-load slide-tray installers.

Why it ranks #9: The 24.5-by-24.5-inch tray supports 200 pounds and locks for travel, but its sliding design serves compartment access, not exterior trailer mounting.

Six access holes let the YANZLAROX tray be positioned and fastened without removing its slide rails, enabling a more direct installation workflow. Dual ball-bearing slides extend fully and support up to 200 pounds, bringing batteries or a generator out for access.

The 24.5-by-24.5-inch overall tray has a smaller listed inner size of 21.8 by 23 by 1.9 inches, so checking the usable interior against the equipment footprint is important. Dual ball-bearing slides provide full extension for wiring, maintenance, and equipment access, while the mechanical lock secures the tray for travel. Six mounting access holes let installers reach the base mounting points with the rails in place, avoiding a rail-removal step during fastening.

Skip it if you need a platform wider than its 21.8-by-23-inch interior; the ONLYLIDA tray measures 24 by 24 inches overall.

Choose this for an RV owner who wants full-extension access for battery wiring or generator maintenance and values rail-in-place mounting. Compare the inner dimensions with the equipment and compartment opening first.

#10

10. ONLYLIDA Steel Slide Tray

• Weight: 31.3 lb

Best for: Steel RV slide-tray users.

Why it ranks #10: This steel platform is described for generators and RV equipment, but the listing gives no load capacity and does not identify an A-frame or trailer-tongue mount.

A sliding steel platform gives the ONLYLIDA RV tray a way to bring generators, batteries, or tools out from their storage position, enabling easier access without treating the tray as a fixed exterior cargo rack. Its 24-by-24-inch footprint is the key fit consideration.

The listing identifies solid steel construction and a 24-by-24-by-2.7-inch tray, a combination suited to carrying equipment on an RV mounting platform. Its slide-out format can make stored gear more accessible for use or maintenance than reaching into a fixed compartment. The product is also described for batteries, generators, toolboxes, and fuel cans, so it can serve several utility-storage roles. Check available mounting and clearance space against the listed dimensions before installation.

Skip it if you need a stated load capacity before selecting a slide tray; the QTSZNDF 22.6-by-13-inch tray lists support up to 264 pounds.

This fits an RV owner seeking a steel slide-out platform for batteries, generators, or tools. Its 24-inch-square footprint and the mounting space available in the RV compartment are the key fit boundaries.
