The Dee Zee DZ91753 sets the benchmark for aluminum transfer tanks. Constructed from 0.125-inch brite-tread aluminum, it eliminates rust concerns—a critical advantage for outdoor storage. With a 110-gallon capacity, it provides massive fuel autonomy for long-haul towing or off-grid equipment operation.

Weighing only 100 pounds empty, this tank is surprisingly light for its size, making it one of the few 100+ gallon tanks a single person can maneuver into a truck bed. The radius curve design eliminates weld pressure points, preventing stress fractures over time. Users consistently report zero leaks after 7-10 years of continuous outdoor exposure in harsh climates like Florida.

One note: this unit is labeled as a “transfer tank,” not an auxiliary tank, meaning it is not approved for direct gravity-fed connection to your vehicle’s fuel system. It is ideal for use with a separate 12V pump to refuel equipment. The cap and coupler allow proper venting during filling and transfer.

For those needing a large, portable solution for gasoline storage, the AM-TANK 116-gallon caddy is a purpose-built unit. It uses roto-molded polyethylene with anti-static and conductive properties specifically rated for gasoline, which is critical—standard diesel caddies cannot safely contain gasoline due to vapor and conductivity differences.

The integrated 13-foot grounding cable and clamp minimize static discharge risks during refueling. The 2-inch filling plug features a three-effect pressure management system (pressure, de-pressure, and overturning protection), while the suction net filter keeps impurities out of your fuel supply. Forklift pockets and integrated handles make transport straightforward even when partially full.

Customer feedback highlights excellent service from the manufacturer, with one user reporting a free replacement tank when a nozzle issue arose. However, a minority experienced pump failures due to loose clamps or electrical issues—so thoroughly checking all fittings and connections upon delivery is essential. This is a DOT-spec compliant unit for legal road transport.

The VEVOR 116-gallon tank delivers high-capacity fuel storage at a price point that undercuts most competitors by a significant margin. Built from UV-resistant LLDPE, it is designed to withstand changing weather conditions without cracking or fading. The red coloration makes it immediately identifiable for gasoline or diesel storage.

A standout feature is the integrated 12V electric transfer pump delivering a 10 GPM flow rate—far faster than manual rotary pumps. The automatic shut-off nozzle prevents overfill spills, a major convenience when refueling in low-light conditions. The duplex filter system catches both large and fine particulates, protecting your equipment from contaminated fuel.

Assembly quality requires attention: multiple customers report loose fasteners, missing screws, and O-rings that need replacement with fuel-rated alternatives. The fuel gauge is also noted as being inaccurate. Budget for some initial troubleshooting (Teflon tape, proper O-rings, tightening all connections) before putting it into regular service.

If you need both fuel storage and tool storage in one footprint, the Dee Zee DZ92647SB is the ultimate space-saving solution. This L-shaped unit combines a 92-gallon fuel tank with a lockable steel toolbox, using 14-gauge steel construction with an NRT powder coat specifically designed to maximize corrosion protection.

Users with full-size trucks like a 2022 Ford F-250 report a perfect fit under a tonneau cover with no leaks even after a full year of use. The toolbox compartment is generous enough to hold 15 chains and binders, a full-size floor jack, and multiple socket sets—a genuine workbench integration for contractors who need tools and fuel on remote job sites.

The biggest concern is the mounting bracket durability. One long-term user reported all brackets snapping off within 30,000 miles, even with a rubber vibration pad installed. Ensure that your installation uses heavy-duty aftermarket brackets or additional reinforcement, especially in trucks that see rough terrain.

The RDS 72771 is a 60-gallon aluminum tank engineered to sit low in a truck bed, which makes it compatible with most tonneau covers. Its rectangular profile—55 x 20 x 12.75 inches—allows for easy side access even with a fifth-wheel hitch installed. The locking automotive-style fill cap adds security against fuel theft.

Installation is straightforward with a helper, though the tank’s actual capacity has been measured by multiple users at around 50-57 gallons, not the advertised 60. The tank comes with mounting tabs that bolt directly to the bed, and the aluminum construction eliminates any rust concerns. Users report that with the correct installation kit, it adds over 50% more range to a standard 34-gallon truck fuel tank.

The primary complaint involves the filler valve inlet being extremely tight, requiring prying to open initially. Additionally, the tank’s vent line and fuel adapter installation can be tight in F-250 short beds, especially with factory bed liners already installed. Budget for some minor field modification during setup.

The RDS 70326 is a 69-gallon rectangular tank built for users who need maximum capacity in a long bed configuration. Measuring 57 x 18 x 16 inches, it is designed for 8-foot truck beds and fits under Bakflip-style folding tonneau covers on Ram 3500 duallys with no interference.

Multiple users with Ram 2018 3500 long bed trucks confirm it provides a perfect fit, significantly extending driving range when towing 33-foot trailers. The machined aluminum finish resists corrosion and the tank includes all necessary mounting tabs. The 69-gallon capacity translates to roughly 480 miles of additional range for a diesel truck towing heavy loads.

Shipping can be a headache: the tank and the installation kit are often shipped separately under the same tracking number, causing confusion and delays. Order well in advance of when you actually need the tank. Some tabs may require slight adjustment for bolt alignment, but overall construction quality is praised as solid and well-designed.

The RDS 72743 is a tool combo unit that integrates a 60-gallon fuel tank with a top-opening lockable toolbox. This design is particularly appealing for 5th wheel owners who want fuel storage without losing bed space for hitch clearance. The tank sits low in the bed and leaves roughly 6 feet 2 inches of remaining bed space in an 8-foot F-350.

Users towing 41-foot fifth wheels report adding 700+ miles of towing range on top of the factory 250-mile range. The bright, shiny aluminum finish requires care during shipping—units may arrive with bent sides or stuck lids due to packaging damage. The lid opens automatically under shock tension, which can be a hazard if not expected.

The tank’s actual capacity is debated: users report filling it to 52-53 gallons, not 60. The installation requires an RDS diesel install kit and can be difficult if a fifth-wheel hitch is already installed. Pre-feeding the gravity line through a 3/4-inch hole before final neoprene placement is recommended. Consider offsetting the tank from the fuel line side.

The AM-TANK 58-gallon version offers the same professional-grade polyethylene construction as its larger sibling but in a more manageable size. With integrated forklift pockets, carrying handles, and a lockable draw-latch lid, it is designed for sites where gasoline needs to be moved between trailers, flatbeds, or storage areas routinely.

The 2-inch filling plug nozzle with a three-effect system manages pressure buildup, allows depressure during refills, and prevents overturning. A 13-foot grounding cable and clamp are included to dissipate static charge. The unit is built from anti-static and conductive polyethylene specifically rated for gasoline storage—never substitute a diesel-only tank for this application.

Customer service from AM-TANK is a notable strength: one user reported a family owning six tanks, and when one had an issue, the company sent a free nozzle and then a replacement tank when the problem persisted. However, the pump switch lacks positive detents and may need a lock to prevent accidental activation during transport. The nozzle can also experience venturi blockage, requiring video proof for warranty claims.

The TITAN 7020217 is a direct replacement mid-ship fuel tank for 2017-2024 Ford F-250 and F-350 crew cab short beds. It replaces the factory 34-gallon tank with a 55-gallon unit, increasing capacity by 21 gallons without taking up any truck bed space. It uses the truck’s stock OEM sending unit and is compatible with aftermarket lift pumps like AirDog and FASS.

Installation takes a couple of hours on a lift and bolts into the factory location. Users report a massive range increase—1,000 miles highway, 800 city—making it ideal for long-distance towing. It does not interfere with powered steps or air bag systems. A critical note: after installation, the truck’s ECU needs a dealer or Forscan reprogramming for the DTE and fuel gauge to read accurately; the truck will not self-calibrate.

The tank is made from high-density polyethylene (HDPE) and is designed exclusively for traditional pickup short beds—not cab & chassis models. One user reported missing hardware due to UPS damage, and Titan refused to replace it, so inspect the package immediately upon delivery. Also, be aware that this tank sticks out lower than the stock tank, and you will lose the FX4 skid plate.

The DNA MOTORING 58-gallon diesel tank is an entry-level polyethylene caddy that comes pre-equipped with a 12V DC electric transfer pump. The pump runs at 140W, 22 amps, and delivers an open flow rate of 40 liters per minute (roughly 10.5 GPM). It includes an automatic dispensing nozzle, a mechanical clock gauge, and 13.1 feet of hose with battery clamps for easy 12V hookup.

The tank’s bottom groove design allows it to be carried with a forklift or by hand in a pickup bed. It is widely used for diesel transport to tractors, trucks, ships, and construction equipment. The grey polyethylene is UV-resistant for extended outdoor service.

Reliability is a mixed bag. Some users report the tank works flawlessly for DEF transport or diesel refueling, praising the fast pump flow. Others report a non-functional manual rotary pump with zero customer support response from DNA Motoring. The fill hole filter can cause gas spray during filling, and the wheel axle in some variants fell off after the second use. This is a budget pick, but with inconsistent quality control.

The RDS 71804 is a compact 37-gallon auxiliary fuel tank that measures just 50 x 20 x 9 inches and weighs 77 pounds empty. Its low profile makes it the best solution for fitting under a cross-bed toolbox in a short-bed truck. The aluminum construction means no rust, and the tank includes pre-drilled mounting tabs for secure installation.

Users confirm it fits 2016 Ram 2500 short beds with tonneau covers, offering an easy installation that requires no drilling for lines or wiring when using the correct vent line adapter and pump to transfer diesel to the factory tank. The tank is narrow enough to allow for fifth-wheel hitch clearance while still adding 37 gallons of diesel capacity.

Be aware of spec discrepancies: one user received a 33-gallon tank instead of 37 gallons, and another found the mounting tabs misaligned. The filler cap arrived broken on one unit due to poor shipping protection on the pallet. Welds are reported as smooth and professional, but overall capacity may vary by up to 4 gallons from the advertised volume. The installation kit is sold separately.

The Flame King YSN420ASME is a 120-gallon (420 lb) ASME-certified vertical propane tank, designed for permanent installation to power home appliances, RVs, or propane generators. It ships empty, pre-purged, and vacuum-sealed, ready for a local propane supplier to fill on-site. The tank comes pre-installed with a propane float gauge, ACME fill valve, service valve, and relief valve.

The advantage of an ASME tank over a DOT cylinder is that it never requires recertification after 12 years—it is a lifetime asset. The high-grade welded steel is powder-coated for rust protection, though the factory primer coating is thin. Owners recommend applying Rustoleum white spray paint for additional UV and weather protection.

Customers report savings of -2 per gallon on propane by owning their own tank instead of renting from a supplier. The tank’s 120-gallon capacity is substantial for whole-home heating or large propane stoves. Delivery companies report being impressed with the build quality. A plastic lid cover protects the valves and gauge from the elements.

The Trailfx 37024153 is a 36-gallon vertical fuel transfer tank machined from extra heavy-duty aluminum tread plate. Its compact dimensions (11 x 17 inches) and low silhouette make it ideal for pickup boxes where space is at a premium, particularly when a fifth-wheel hitch occupies the center of the bed. It includes a lockable cap, a coupler which allows venting, and a recessed drain plug.

Users report it being a perfect fit for their trucks, using it to transport diesel for excavators and skid steers without leaks. One user noted it doubles fuel capacity and was bolted down securely for off-road use. The aluminum tread plate construction gives it a rugged, durable feel that resists dents and corrosion.

A significant concern is capacity accuracy: one customer reported the tank only holds 25 gallons, not the advertised 36, and found the seller unresponsive. Another rated it 5/5 with no capacity complaints. The 30-day manufacturer warranty from Better Built is short, so verify the capacity immediately upon receipt by filling it with a measured amount of fuel.
