Best Reserve Fuel Tank For Truck Bed

#1 · Best Overall

1. Dee Zee DZ92647B Combo

• Dimensions: 32.75"W x 25.38"H
• Weight: 138 lb
• Capacity: 92 gallons
• Material: Aluminum

Best for: High-capacity bed storage.

Why it ranks #1: Its 92-gallon aluminum tank combines fuel storage and a toolbox, with three stability baffles and a lockable cap listed in the description.

The 92-gallon capacity is paired with an integrated toolbox, letting truck owners carry a substantial liquid reserve while keeping tools in the same bed-mounted unit. Its L-shape measures 46.75 by 32.75 by 25.375 inches, and the .125-inch Brite-Tread aluminum body has a protective black powder-coat finish.

Three stability baffles help steady the liquid during transport, while the radius-curve design reduces pressure at key weld points. A lockable cap adds a security measure, and the .375-inch drainage plug gives owners a defined drain point for maintenance. The venting coupler supports tank venting. The integrated toolbox adds storage alongside the 92-gallon tank, but its L-shaped dimensions and 138-pound empty weight make bed space and payload planning important.

Skip it if you need a lighter, smaller reserve; the 138-pound tank and 92-gallon footprint may use more payload and bed space than your setup allows.

Truck owners seeking a large reserve with tool storage in one unit will value this combo. Check that its 46.75-by-32.75-inch L-shaped footprint and 138-pound empty weight suit your bed and payload limits.

#2 · Auxiliary Fueling

2. RDS 72548 Combo

• Weight: 16 oz
• Capacity: 60 gallons
• Material: Alloy Steel, Aluminum, Stainless Steel

Best for: Auxiliary-fuel combo users.

Why it ranks #2: This 60-gallon truck-compatible combo is described as supporting auxiliary fueling, with diesel gravity-feed capability and an optional install kit.

The 60-gallon RDS tank combines transfer-tank and auxiliary-fuel roles with a toolbox, enabling truck owners to carry reserve fuel and tools together. Its listed dimensions are 55 by 20 by 19.5 inches, and the product information notes that RDS tanks can connect to a vehicle’s fuel tank.

For diesel auxiliary fueling, the description says fuel can gravity-feed from the bottom of the RDS tank, with an optional Diesel Install Kit mentioned for installation. That makes the auxiliary connection relevant to buyers planning a vehicle fuel-system setup, rather than only storing fuel in the bed. The 60-gallon capacity and 55-by-20-inch footprint help frame the reserve and space tradeoff; the listing does not provide a pump flow rate.

Skip it if you want a listed powered transfer pump and flow rate; the Vigorighter 60 Gallon Aluminum Fuel Transfer Tank Toolbox Combo includes a 12 GPM pump.

Choose this RDS combo if auxiliary fueling and integrated tool storage matter alongside a 60-gallon reserve. Buyers planning gasoline auxiliary use need an electric pump for top siphoning, and should account for the listed 55-by-20-inch footprint.

#3 · Pump Included

3. Vigorighter 60-Gallon Combo

• Dimensions: 50.2"W x 24.8"H
• Weight: 85 lb
• Capacity: 60 gallons
• Material: Aluminum

Best for: Powered toolbox combo.

Why it ranks #3: The aluminum 60-gallon tank pairs a built-in toolbox with a 12-volt pump rated at 12 GPM for buyers seeking an integrated transfer setup.

A built-in 12V DC pump rated at 12 GPM lets this 60-gallon tank transfer fuel directly from the truck bed. The aluminum tank and integrated tool compartment combine reserve storage and work gear in one unit, with overall dimensions of 50.2 by 19.88 by 24.8 inches.

The 12 GPM pump supports a quicker transfer workflow than handling fuel without a listed powered pump, while the 60-gallon capacity carries a sizable supply for trucks and work sites. Aluminum construction is described as corrosion-resistant and lightweight, helping keep the tank's listed empty weight to 85 pounds. A 31-by-19.88-by-9.5-inch tool compartment puts storage within the same bed footprint, so tools and fuel travel together.

Skip it if you need more than 60 gallons in one tank; the VEVOR Portable Diesel Tank 116 Gallon Capacity offers a listed 116-gallon capacity.

Work crews wanting a powered 60-gallon reserve and integrated tool storage can use this as an all-in-one bed setup. Its 50.2-inch length and 85-pound empty weight remain important fit and payload considerations.

#4

4. Vigorighter 51-Gallon Combo

• Dimensions: 19"W x 21"H
• Capacity: 51 gallons
• Material: Aluminum

Best for: Pumped fuel and tool storage.

Why it ranks #4: Its 51-gallon aluminum tank includes a toolbox, 12 GPM pump, 13-foot hose, and auto nozzle, combining storage and transfer equipment.

The included 12V DC pump is rated at 12 GPM, giving this 51-gallon aluminum combo a powered transfer setup alongside a built-in toolbox. At 50 inches long, 19 inches wide, and 21 inches high, it combines fuel, tools, and cargo within one truck-bed unit.

A 13-foot hose and auto nozzle extend the pump setup for transferring fuel, while the 12 GPM rating supports a brisk workflow. The toolbox measures 31 by 19 by 8.8 inches, providing a defined space for tools without a separate box. Corrosion-resistant aluminum forms the tank and toolbox body. During pumping, the listed pressure-relief valve must be open to prevent vacuum collapse; the instructions also say to open it periodically during long-term storage.

Skip it if you prefer a setup without a required valve-opening step; this tank's instructions require the pressure-relief valve open while pumping fuel.

This combo fits truck owners seeking a powered 51-gallon reserve with a toolbox, hose, and auto nozzle. Keep the required pressure-relief-valve step in mind, and check that its 50-inch length and 21-inch height suit your bed.

#5 · Steel Construction

5. Dee Zee DZ92556NSB

• Dimensions: 59.5"W x 19"H
• Weight: 70 lb
• Capacity: 128 liters
• Material: Alloy Steel

Best for: Steel tank bed haulers.

Why it ranks #5: This bed-oriented 42-gallon steel tank has five stability baffles, mounting tabs, a drain plug, and a listed three-year limited warranty.

Five stability baffles help manage fuel movement in this 42-gallon, heavy-duty 14-gauge steel Dee Zee tank. Its 59.5-inch width and 19-inch height give truck owners a long, low-profile reserve option, while mounting tabs provide points to secure it to the truck bed.

The radius-curve construction is described as eliminating key weld pressure points, complementing the steel body for a sturdy transport setup. Five baffles address shifting contents, and the included drain plug provides a maintenance point. A lockable cap adds security, while the black NRT rust-inhibitor powder-coat finish protects the steel surface. At 70 pounds empty, the tank's steel construction and 42-gallon capacity make payload and available bed length the main planning factors.

Skip it if you need a larger reserve than 42 gallons or cannot allocate nearly five feet of bed width to the tank.

This Dee Zee suits truck owners who want a steel 42-gallon tank with baffles, mounting tabs, and a lockable cap. Its 59.5-inch width, 70-pound empty weight, and steel construction should suit the bed and payload plan.

6. Better Built 36-Gallon Tank

• Dimensions: 11"W x 17"H
• Weight: 40 lb
• Capacity: 36 gallons
• Material: Alloy Steel

Best for: Controlled steel fuel transfer.

Why it ranks #6: Its 36-gallon steel design includes baffles, a lockable cap, mounting kit, and an overfill restriction that automatically shuts off at the pump.

An overfill restriction automatically shuts off the pump to help prevent spills, making this 36-gallon Better Built steel tank a practical choice for controlled refueling. Built-in baffles add strength and help prevent contents from shifting, while a lockable cap adds security during transport.

The 2-inch-diameter flush-mounted inlet and outlet bungs are specified for fast flow, supporting a more direct transfer setup. The automatic overfill restriction helps limit spills at the pump, and the baffles address both tank strength and movement of contents in transit. A vented lockable cap and included mounting kit with rubber bushings complete the listed hardware. The rectangular steel tank holds 36 gallons, so buyers can weigh its capacity against the fuel reserve they need.

Skip it if you need more than 36 gallons of reserve in one tank; this rectangular steel model is limited to 36 gallons.

Truck owners prioritizing controlled refueling, baffles, and a lockable cap can consider this 36-gallon steel tank. Its capacity and 11-by-17-inch listed dimensions should match the intended reserve and available bed space.

#7 · Largest Listed Aluminum

7. RDS 69-Gallon Tank

• Weight: 16 oz
• Capacity: 69 gallons
• Material: Aluminum

Best for: Large aluminum auxiliary reserve.

Why it ranks #7: This 69-gallon rectangular aluminum auxiliary tank offers substantial capacity; the listing describes diesel gravity feed and gasoline siphoning from the top.

The 69-gallon capacity gives this rectangular RDS aluminum tank a substantial auxiliary reserve in a 57-by-18-by-16-inch package. The listing describes diesel gravity-feeding from the tank bottom when connected to a vehicle fuel tank, making it relevant to buyers planning auxiliary fueling.

The aluminum construction and rectangular dimensions provide a defined fit profile for truck-bed storage, while the 69-gallon capacity carries a sizeable reserve. RDS says its auxiliary tanks connect to a vehicle’s fuel tank, and that diesel can gravity-feed from the bottom of the tank. Gasoline auxiliary fueling is also allowed, but the listing specifies siphoning from the top with an electric fuel pump. That distinction affects the installation and transfer method buyers need to plan.

Skip it if you want gasoline auxiliary fueling without providing an electric pump; the listed method requires top siphoning.

This RDS tank suits buyers seeking a 69-gallon aluminum reserve and planning an auxiliary vehicle-fuel connection. Diesel gravity feed is described from the bottom; gasoline use requires top siphoning with an electric pump.

#8

8. Landrol 58-Gallon Tank

• Capacity: 58 gallons
• Material: Aluminum

Best for: Gauge-ready auxiliary storage.

Why it ranks #8: The 58-gallon aluminum tank includes mounting brackets and straps, but its listing explicitly says it is not DOT certified.

A sending unit connects to a fuel gauge, helping drivers check the remaining capacity in this 58-gallon aluminum tank. The 59-by-13-by-17-inch rectangular profile provides a narrow footprint for truck-bed storage, while oil pipes and vent covers are also listed as included features.

The sending unit's connection to a fuel gauge gives the driver a way to monitor fuel remaining, and the 58-gallon capacity offers a substantial reserve. Aluminum construction is described as easy to clean, while manually welded joints and reinforcing covers are cited for strength. Fully welded mounting brackets support installation on a truck, and two straps make removal from the vehicle quicker. The listing explicitly notes that this tank is not DOT certified, a key compliance consideration.

Skip it if you require a DOT-certified tank; the listing explicitly says this Landrol tank has not been certified by DOT.

This Landrol suits truck owners wanting a 58-gallon aluminum tank with gauge connection and removable mounting. Its explicit lack of DOT certification is a decisive boundary, so account for that before choosing it for transport.

#9

9. CAMMOO 58-Gallon Portable Tank

• Dimensions: 26.4"W x 26.2"H
• Weight: 68.8 lb
• Capacity: 58 gallons
• Material: Aluminum, High Density Polyethylene (HDPE)…

Best for: Portable diesel reserve.

Why it ranks #9: This portable diesel tank lists a 13.2 GPM pump and 58-gallon capacity, but its portable plastic construction is less directly aligned with a fixed bed tank.

A listed 58-gallon capacity and 13.2 GPM 12V DC pump give this CAMMOO portable diesel tank substantial reserve volume with powered transfer. Its flame-retardant LLDPE and HDPE construction is specified for outdoor use, with resistance to UV, rain, snow, wear, and corrosion.

The 12V pump's 13.2 GPM rating supports moving diesel from the portable tank, while the 58-gallon capacity extends the amount carried between refills. A combo lock provides a way to secure access to stored fuel. The stated outdoor-material protections address exposure to weather and wear, and the listing specifies a fuel-filled operating range of 14°F to 104°F. That temperature boundary is important for buyers planning seasonal or cold-weather use.

Skip it if you need to keep fuel inside the tank below 14°F or above 104°F; its stated operating range ends at those temperatures.

Diesel users seeking a portable 58-gallon reserve and powered transfer can consider this CAMMOO tank. Its stated 14°F-to-104°F operating range with fuel inside is a key boundary for buyers facing temperature extremes.

#10

10. VEVOR 116-Gallon Portable Tank

• Dimensions: 28.3"W x 28.9"H
• Weight: 104.1 lb
• Capacity: 400 gallons
• Material: Polyethylene (PE)

Best for: Large-volume diesel transport.

Why it ranks #10: Its 116-gallon polyethylene diesel tank and 10.6 GPM pump offer high portable capacity, but it is less specifically suited to a conventional bed-mounted reserve tank.

The 116-gallon capacity gives this VEVOR portable diesel tank a substantial reserve for work that demands more fuel on hand. Its 12V DC pump is rated at 10.6 GPM, and the 13.1-foot hose and electric wire provide reach for a truck-bed transfer setup.

The 10.6 GPM pump and 13.1-foot hose support moving diesel from the tank without relying on an unpowered transfer process. A polyethylene body is specified as weather-resistant and UV-resistant, and its 6 mm thickness reaches 12 mm at the thickest part. The upper lid locks with a copper lock, adding a security measure for stored fuel. At 104.1 pounds empty, the large-capacity tank requires truck-bed and payload planning.

Skip it if you cannot allocate the payload for a 104.1-pound empty tank; the 116-gallon capacity also calls for substantial bed space.

Choose this VEVOR for diesel jobs where a 116-gallon reserve and 10.6 GPM powered transfer are priorities. Its 104.1-pound empty weight, large tank size, and diesel-specific listing make payload and use planning essential.
