Best 30 lb Propane Tank For RV: Compare 10 Options

#1 · Best Overall

1. Flame King Dual 30 lb RV Kit

Best for: Complete dual-tank RV kit.

Why it ranks #1: Includes two 30 lb steel tanks, an auto-changeover regulator with 12-inch pigtails, and a dual RV tank rack for a coordinated setup.

Two 30-pound cylinders, an auto-changeover regulator, pigtails, and a dual-tank rack arrive together in this Flame King kit. That combination supports an RV owner setting up paired propane storage without sourcing each listed core component separately.

Each steel tank has an OPD valve and powder-coated finish, pairing overfill protection with the listed rust-protection treatment. The two-cylinder arrangement connects to the included auto-changeover regulator and 12-inch pigtails, while the dual RV rack provides the stated mounting component. Both tanks are pre-purged and supplied empty, so filling remains necessary before use. Since the kit contains two 30-pound cylinders, buyers should account for the space and handling demands of a paired setup rather than a single-tank installation.

Skip it if you need only one cylinder and already have mounting hardware; the Flame King YSN301 offers a single 30-pound tank.

Choose this for an RV owner assembling a paired-tank system who wants the rack, pigtails, and auto-changeover regulator included. It is a two-cylinder kit, so available mounting space matters.

#2 · Best RV Replacement

2. NF1175 Horizontal RV Tank

Best for: Horizontal motorhome replacement.

Why it ranks #2: Explicitly intended for RV motorhomes as a horizontal replacement, with a stated 6.8-gallon capacity and 23.4-inch length.

The NF1175 horizontal vapor-type format is identified as a replacement for Manchester 1175 tanks, giving motorhome owners a specific replacement path to investigate. Its 30-pound capacity and listed 6.8-gallon volume suit buyers seeking a horizontal RV cylinder rather than a standard upright tank.

At 23.4 inches long and 12.2 inches in diameter, the stated dimensions give owners measurements to compare with an existing horizontal installation. The listing also identifies compatibility with most gas barbecue grills, heaters, and stoves, extending its stated uses beyond motorhomes. A built-in overcurrent protection device is described as cutting off gas when abnormal airflow is detected. The pressure regulator is said to adapt to tank pressure changes to maintain stable output, supporting steadier appliance operation as fuel level changes.

Skip it if you want a horizontal tank with an integrated gauge and bolt-down option; the Flame King YSN301HZL lists both.

This is aimed at motorhome owners replacing a Manchester 1175 vapor-type horizontal tank, with listed dimensions and regulator details to compare. Confirm the existing installation’s required format and space.

Listed on Amazon as: NF1175 30lb Horizontal Propane Tank, for RV Motorhome, Replacement Manchester 1175 Vapor Type, Low Profile Horizontal Propane Tank, 6.8 Gallon Capacity, 23.4" Length 12.2" Diameter, 31lbs Tare Weight

#3 · Best Horizontal Tank

3. Flame King YSN301HZL

• Weight: 25.5 lb

Best for: Horizontal RV installation.

Why it ranks #3: A 30 lb horizontal cylinder listed for RVs and truck campers, with an OPD valve, built-in gauge, bracket feet, and bolt-down option.

A low-profile horizontal shape is the defining feature of this Flame King 30-pound cylinder, making it a candidate for RVs and truck campers that use horizontal tanks. Its built-in gauge gives a visible fuel-level reading, while the integrated handle and bracket feet address handling and stable placement.

The Type 1 OPD valve provides overfill protection, and the gauge lets owners check the indicated propane level without relying only on elapsed use. A formed collar handle without sharp edges supports carrying, while stable bracket feet and a bolt-down option offer placement choices for compatible installations. The listing names RVs, truck campers, patio heaters, fire tables, and barbecues as uses. Keep the cylinder upright and observe the stated propane safety guidance.

Skip it if you need two cylinders, a regulator, pigtails, and a rack together; the Flame King FK-30LBT kit bundles those RV components.

Consider it for an RV or truck camper already set up for a horizontal cylinder, especially when a visible gauge and securing options matter. Its listed low-profile format is the key installation boundary.

#4 · Best Covered Setup

4. Flame King Tank and Cover

Best for: Tank and dual-cover bundle.

Why it ranks #4: Pairs a 30 lb tank with a gauge and OPD valve with a dual 30 lb tank cover; listed for RVs and trailers.

A built-in propane gauge paired with a dual 30-pound tank cover gives this Flame King bundle a clear RV storage focus. The gauge supports checking fuel levels, while the cover is described as protecting two tanks, making the combination relevant to paired outdoor propane setups.

The 30-pound steel tank is pre-purged and has a powder-coated finish, with an OPD valve for overfill protection and stated rust protection. DOT and Transport Canada certification support the listing’s transport credentials, and the standard-size connection valve is described as compatible with RVs, trailers, and propane heaters. The heavy-duty polypropylene cover is intended for two 30-pound tanks, so its protective role suits a paired arrangement; the supplied description does not list a second tank as included.

Skip it if you want two cylinders plus a regulator, pigtails, and rack; the Flame King FK-30LBT kit lists those components.

Pick this for an RV or trailer owner wanting a gauge-equipped 30-pound tank and a cover sized for two tanks. The listing describes one tank, so a second cylinder is a separate consideration.

#5

5. Flame King YSN-301

Best for: Refill-ready vertical RV tank.

Why it ranks #5: A DOT- and Transport Canada-certified 30 lb steel cylinder with an OPD valve, but the listing does not specify horizontal RV installation.

A pre-purged, vacuum-ready interior means this 30-pound Flame King tank can go straight to propane filling rather than requiring a separate purge. Its welded-steel construction and powder-coated finish suit RV owners seeking a conventional vertical cylinder with stated corrosion protection and transport certifications.

The Type 1 OPD valve helps prevent overfilling, an important practical feature when arranging refills at locations that require OPD-equipped tanks. X-ray and hydrostatic testing, along with DOT and Transport Canada certification, support transport in the United States and Canada. At 30-pound capacity, it provides a larger storage option than smaller cylinders, while the pre-purged vacuum interior keeps the initial filling step straightforward. The listing specifies an empty tank, so propane must be obtained separately.

Skip it if you need a complete two-cylinder RV setup; the Flame King FK-30LBT kit includes two tanks, a regulator, pigtails, and a rack.

Choose this for an RV owner who wants one refill-ready 30-pound vertical cylinder with stated transport certifications. It arrives empty, and the listing does not specify included mounting hardware or a regulator.

#6

6. Flame King YSN330 Rack Bundle

Best for: Gauge-equipped RV tank setup.

Why it ranks #6: Combines a gauged 30 lb tank with a dual RV tank rack; the listing clarifies that tanks are sold separately, limiting bundle completeness.

A built-in gas meter gauge is the key feature of this Flame King listing, giving owners an on-tank reading of propane level. The listing pairs a 30-pound steel cylinder with a dual RV tank rack, addressing fuel checks and tank mounting in one offering.

The tank is described as pre-purged, welded steel with a powder-coated finish, supporting filling readiness and the stated rust-prevention treatment. Its OPD valve provides overfill protection, while the gauge gives a visible level indication for planning refills. The listing also names a dual-cylinder rack for RVs and trailers, but explicitly says tanks are sold separately. Buyers therefore need to account for sourcing the cylinder or cylinders independently of the rack rather than assuming the title’s tank-and-rack wording means both are included.

Skip it if you want two tanks, a regulator, pigtails, and a rack in one kit; the Flame King FK-30LBT includes those components.

This suits RV or trailer owners prioritizing a gauge and dual-tank mounting option, provided they account for the separate tank purchase. It is not the all-in-one paired-cylinder kit described elsewhere.

#7

7. SupplyMount YSN301HZL

• Weight: 27 lb

Best for: Flame King-compatible replacement.

Why it ranks #7: A 30 lb horizontal replacement cylinder compatible with Flame King YSN301HZL, but buyers are told to verify the part number with vehicle specifications.

A direct-fit replacement claim for the YSN301HZL model gives this SupplyMount cylinder a specific audience: owners replacing that horizontal propane-cylinder model. The listing describes it as an aftermarket component intended for straightforward installation, rather than a general-purpose RV tank bundle.

The named YSN301HZL model reference helps buyers identify the replacement target, while the direct-fit wording points to an installation-oriented use case. SupplyMount describes the construction as using materials intended for long-term performance and wear resistance in demanding automotive applications. The listing also says it is designed to meet automotive industry specifications, but provides no further specification details here. Its 27-pound item weight is useful when considering handling; verify the relevant vehicle specifications before ordering, as the listing advises.

Skip it if you want a horizontal tank with listed capacity, gauge, and mounting feet; the Flame King YSN301HZL supplies those feature details.

Consider this only when replacing the specifically named YSN301HZL horizontal cylinder and the aftermarket replacement claim matches your application. The supplied listing gives limited tank specifications beyond model and weight.

#8

8. Generic 30 lb Steel Cylinder

• Weight: 24 lb

Best for: Simple 30-pound cylinder.

Why it ranks #8: A DOT-approved steel 30 lb cylinder with OPD valve and stated 7.1-gallon capacity, but no RV orientation or mounting details are supplied.

A listed 7.1-gallon capacity gives this 30-pound steel LP cylinder a clearly stated storage figure for RV travel and other extended-use applications. Its OPD valve and DOT approval make it a straightforward option for buyers who want a basic certified tank rather than a bundled RV hardware kit.

The product description identifies RV travel and larger grills as extended-use applications, so its 30-pound capacity suits buyers seeking more propane storage than a small cylinder offers. The OPD valve provides overfill protection, while DOT approval addresses highway transport and refilling eligibility as described in the listing. Its stated dimensions are 12.3 inches by 12.3 inches by 23.4 inches, useful when checking the available storage space. The listing describes a cylinder, not accompanying regulator or rack components.

Skip it if you want a visible level gauge on the tank; the Flame King YSN330 lists a built-in gas meter gauge.

This fits RV travelers or grill owners seeking a basic 30-pound cylinder with a stated gallon capacity and DOT approval. Check the listed dimensions against the intended storage space before choosing.

#9

9. Cooking Station 30 lb Tank

• Weight: 13.5 lb

Best for: DOT-approved refill option.

Why it ranks #9: Provides a 30 lb capacity, DOT approval, and OPD valve, but its listing emphasizes general outdoor equipment rather than RV installation.

DOT approval is the clearest practical marker on this 30-pound Cooking Station tank, with the listing stating highway transport and refills at authorized propane stations. Its OPD valve adds overfill protection, making it a simple cylinder choice for campers and outdoor propane equipment.

The 30-pound capacity provides the higher-volume fuel storage the listing associates with outdoor propane equipment, campers, and appliances, reducing the need for frequent refilling relative to smaller capacities. DOT approval is specifically cited for highway transport and authorized-station refills. The built-in OPD valve is intended to prevent overfilling, while the brass valve construction is described as durable. At 12 inches wide and 24 inches high, its dimensions give buyers concrete figures for checking storage clearance.

Skip it if you want to check fuel level with an onboard gauge; the Flame King YSN330 includes a built-in gas meter gauge.

Choose it if you need a DOT-approved 30-pound cylinder for a camper or outdoor appliance and value stated refill compatibility. Its 12-by-24-inch dimensions remain a practical storage consideration.

#10

10. Crown Verity CYL-30H

• Weight: 33.4 lb

Best for: Club grill horizontal tank.

Why it ranks #10: Although it is a 30 lb horizontal tank, the listing identifies it for a club grill, not RV use, making it the weakest match.

The listing specifically assigns this 30-pound horizontal Crown Verity tank to club grills, making that use case more precise than general RV claims. Buyers with that equipment can focus on the horizontal format and 30-pound size when assessing whether it suits their setup.

Crown Verity identifies the CYL-30H as a 30-pound horizontal tank and states that all tanks ship empty, so filling is a necessary step before operation. Its additional description distinguishes uses by size, naming 30-pound horizontal tanks for club grills; that is the clearest compatibility guidance supplied. The listing does not provide further valve, gauge, or installation details, so buyers should not assume those features from the product name alone. The stated item weight is 33.4 pounds, relevant for handling.

Skip it if you need a horizontal tank specifically described for RVs and motorhomes; the Generic NF1175 listing names those applications.

This is the clearest fit for a buyer seeking a 30-pound horizontal cylinder for a club grill. Its listed use is narrower than an RV-specific replacement, and it ships empty.
