Best Transfer Tanks For Pickups: Compare 10 Options

#1 · Best Overall

1. Better Built 36-Gallon Tank

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

Best for: Baffled 36-Gallon Steel Hauling.

Why it ranks #1: A clearly specified 36-gallon steel pickup tank includes mounting hardware, a lockable vented cap, baffles, and an overfill restriction with automatic pump shutoff.

A 36-gallon capacity paired with built-in baffles gives this Better Built tank room for a substantial fuel supply while helping limit contents shifting in transit. Its automatic overfill restriction shuts off at the pump, adding a practical spill-control step for pickup owners who regularly refill equipment away from base.

The alloy-steel tank measures 11 inches wide by 17 inches high, useful dimensions to consider when planning bed space and mounting. Flush-mounted 2-inch inlet and outlet bungs support fast flow, while the included mounting kit with rubber bushings helps with installation. A vented, lockable cap adds security, and the overfill restriction automatically shuts off at the pump. Together, those details suit users who want a relatively compact 36-gallon tank with straightforward refueling features.

Skip it if you need more than 36 gallons aboard; Dee Zee DZ91753 offers a listed 110-gallon capacity.

For pickup owners seeking a baffled steel tank with pump-side overfill control, this 36-gallon model balances capacity and compact stated dimensions. Check that its 11-inch width and mounting arrangement work with your available bed space.

#2 · Best Mid-Size Steel

2. Dee Zee 42-Gallon Steel Tank

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

Best for: 42-Gallon Powder-Coated Steel Hauling.

Why it ranks #2: Its 42-gallon steel design combines five stability baffles, mounting tabs, a drain plug, and a three-year limited warranty.

A radius-curve body and five stability baffles distinguish this 42-gallon Dee Zee steel tank, combining a shape intended to eliminate weld pressure points with features that help steady liquid during transport. Its black NRT rust-inhibitor powder coat also gives pickup owners a protective finish for regular hauling.

The 14-gauge alloy-steel construction and radius curves address structural details, while five stability baffles help control liquid movement on the road. Mounting tabs secure the tank to a truck bed, and the 59.5-inch width and 19-inch height are useful measurements for planning placement. A 3/8-inch drainage plug supports draining, and the lockable cap adds security. Its 42-gallon capacity suits buyers prioritizing steel construction without moving to a larger-volume tank.

Skip it if you need maximum listed capacity and lighter aluminum construction; Dee Zee DZ91753 has a 110-gallon capacity and aluminum body.

This Dee Zee fits pickup owners who want a mid-capacity steel tank with baffles, bed-mounting tabs, and a drain plug. Plan around its 59.5-inch width and 70-pound listed weight before selecting a bed location.

#3 · Best Aluminum Tank

3. RDS 45-Gallon Aluminum Tank

• Weight: 42 lb
• Capacity: 45 gallons
• Material: Aluminum

Best for: 45-Gallon Non-Rusting Auxiliary Tank.

Why it ranks #3: This 45-gallon aluminum tank weighs 42 pounds, has fully welded seams, and supports auxiliary fueling with specified installation conditions.

A 45-gallon aluminum body with fully welded seams gives the RDS 71083 a non-rusting rectangular option for pickup owners carrying fuel. The listing also describes auxiliary fueling: diesel can gravity-feed from the tank bottom, while gasoline auxiliary fueling is allowed when an electric pump siphons it from the top.

The aluminum construction and fully welded seams support a durable tank body, while its 45-gallon capacity offers a mid-sized onboard reserve. RDS describes diesel gravity feed from the bottom for auxiliary connection to a vehicle fuel tank, with an optional diesel installation kit available. Gasoline auxiliary use follows a different method: siphoning from the top with an electric fuel pump. That distinction matters when choosing the installation and operating workflow.

Skip it if you need an included powered pump and hose; EROMMY's 47-gallon dual-fuel tank lists a 12V pump and 13.1-foot hose.

The RDS 71083 suits owners seeking an aluminum auxiliary/transfer tank and willing to follow the distinct fuel-feed methods listed for diesel and gasoline. Consider the optional diesel installation kit when planning vehicle-tank connection.

#4 · Best L-Shape

4. Weather Guard 90-Gallon Tank

• Weight: 196 lb
• Capacity: 90 gallons
• Material: Alloy Steel

Best for: L-Shape Full-Size Truck Fit.

Why it ranks #4: The 90-gallon L-shaped, 12-gauge steel tank is designed for full-size trucks with gull-wing or saddle boxes and includes interior baffles.

An L-shaped 90-gallon tank is specifically described for full-size trucks with Gull Wing or Saddle Boxes, giving owners a fit-oriented option for transporting diesel or hydraulic fluid. Its 12-gauge steel body, interior baffles, drain port, and 2-inch NPT connection support hauling and pump setup.

The L-shape is the key layout consideration for pairing this tank with the listed Gull Wing or Saddle Boxes, while the 90-gallon capacity provides substantial fluid storage. Heavy-duty 12-gauge alloy steel supplies the stated construction, and interior baffles minimize fluid motion during transport. A 3/8-inch drain port supports routine cleaning, and the 2-inch NPT connection eases pump connection. At 196 pounds, the listed weight is an important factor when planning installation and bed loading.

Skip it if you want a lighter listed steel tank; Better Built model 29211584 weighs 40 pounds and has a 36-gallon capacity.

This Weather Guard fits full-size truck owners pairing an L-shaped tank with Gull Wing or Saddle Boxes and needing diesel or hydraulic-fluid capacity. Its 196-pound listed weight and configuration should guide installation planning.

#5 · Highest Capacity Steel

5. Dee Zee 108-Gallon Steel Tank

• Dimensions: 24"W x 24"H
• Weight: 160 lb
• Capacity: 108 gallons
• Material: Alloy Steel

Best for: Black Steel High-Capacity Hauling.

Why it ranks #5: Its listed capacity is 108 gallons, with 14-gauge steel, a corrosion-protective black powder coat, a lockable cap, and a stability baffle.

A listed 108-gallon capacity and 14-gauge steel construction make the Dee Zee DZ91753SB a high-volume choice for hauling non-flammable liquids such as diesel. Its black powder-coat finish provides corrosion protection, while the radius-curve design addresses weld pressure points in the rectangular tank body.

The rectangular tank measures 48 by 24 by 24 inches, a defined footprint to compare with pickup-bed space, and weighs 160 pounds. Heavy-duty 14-gauge steel supplies the body, while the textured black powder coat and NRT rust-inhibitor finish support corrosion protection. The radius curve eliminates weld pressure points, and the listed stability baffle helps limit fluid movement. A lockable cap and 3/8-inch drain plug add security and a maintenance route for diesel transport.

Skip it if you prefer a non-rusting aluminum body; Dee Zee DZ91753 uses Brite-Tread aluminum and lists a 110-gallon capacity.

This Dee Zee suits pickup operators needing high-volume diesel storage in a black steel tank with a drain and stability baffle. Its 48-by-24-inch footprint and 160-pound weight are important bed and mounting considerations.

#6

6. Dee Zee 110-Gallon Aluminum Tank

• Dimensions: 24"W x 24"H
• Weight: 100 lb
• Capacity: 110 gallons
• Material: Aluminum

Best for: High-Capacity Aluminum Fleet Hauling.

Why it ranks #6: The 110-gallon aluminum tank offers a large non-rusting capacity, three stability baffles, mounting tabs, a lockable cap, and a venting coupler.

A listed 110-gallon capacity in non-rusting Brite-Tread aluminum makes the Dee Zee DZ91753 a substantial reserve for pickup owners refueling equipment at remote work sites. Its radius-curve design addresses weld pressure points, while mounting tabs provide a way to secure the rectangular tank to the truck bed.

The 48-by-24-by-24-inch rectangular form provides a clear footprint to compare against truck-bed space, and mounting tabs support securing it in place. Three stability baffles help limit liquid movement, while the 3/8-inch drain plug provides a route for draining during maintenance. A venting coupler and included cap support venting, and the lockable cap adds security. Aluminum construction avoids rusting, a relevant benefit for buyers seeking a large-capacity tank without a steel body.

Skip it if you need a steel tank with a black protective finish; Dee Zee DZ91753SB uses 14-gauge steel and a powder coat.

Choose this Dee Zee for high-volume transport of non-flammable liquids when aluminum construction and bed-mounted storage suit the job. Its 48-by-24-inch footprint and 100-pound listed weight merit checking against available space and mounting plans.

#7

7. VEVOR 116-Gallon Diesel Tank

• Dimensions: 28.3"W x 28.9"H
• Weight: 104.1 lb
• Capacity: 116 gallons
• Material: Polyethylene (PE)

Best for: Powered 116-Gallon Diesel Refueling.

Why it ranks #7: This 116-gallon polyethylene diesel tank includes a 12V pump rated up to 10.6 GPM, a 13.1-foot hose, and a lockable lid.

A 12-volt pump rated at up to 10.6 gallons per minute pairs with this 116-gallon polyethylene tank, enabling powered diesel transfer from a portable pickup-bed supply. Its weather- and UV-resistant construction, lockable upper lid, and included 13.1-foot hose address outdoor use and refueling reach.

The tank's 6-millimeter thickness, reaching 12 millimeters at its thickest point, accompanies polyethylene construction that resists UV radiation and changing weather conditions. A 12V DC pump provides up to 10.6 GPM, while the 13.1-foot hose and 13.1-foot electric wire give the setup stated reach for operating and refueling. At 116 gallons, it supports substantial diesel storage, but its 41-by-28.4-by-29-inch stated dimensions require a suitable bed footprint.

Skip it if you need a dual-fuel gasoline and diesel transfer tank; EROMMY's 47-gallon tank lists both fuel types.

This VEVOR suits diesel users needing substantial portable capacity and powered transfer with a 13.1-foot hose. Its 116-gallon size and stated footprint make bed-space planning essential, and the supplied fuel specification is diesel.

#8

8. EROMMY 47-Gallon Pump Tank

• Dimensions: 13"W x 21.7"H
• Weight: 66 lb
• Capacity: 47 gallons
• Material: Polyethylene (PE)

Best for: Slim Dual-Fuel Farm Refueling.

Why it ranks #8: The 47-gallon polyethylene tank has a slim 13-inch listed width and includes a 12V electric pump, auto-shutoff nozzle, and hose.

A 13-inch-wide, 47-gallon polyethylene tank preserves pickup-bed space while carrying a 12V electric pump for gasoline or diesel transfer. The pump moves fuel at up to 10 GPM, and the listed auto-shutoff nozzle and 13.1-foot hose support a refueling workflow aimed at farms, jobsites, generators, and service vehicles.

Its 35.8-by-13-by-21.7-inch measurements give bed planners a specific slim footprint to assess, while polyethylene construction keeps the tank material distinct from steel options. The 250W copper-wound brushed motor powers transfer at up to 10 GPM, and the 9.8-foot self-priming and 19.7-foot lift figures describe operating reach. An auto-shutoff nozzle and 13.1-foot hose support controlled delivery to equipment; the 47-gallon capacity suits mobile rather than very high-volume needs.

Skip it if you need more than 47 gallons per load; VEVOR's 116-gallon portable diesel tank carries substantially more, though it is specified for diesel.

For farm and jobsite users needing powered gasoline or diesel refueling in a slim pickup-bed footprint, EROMMY combines pump, hose, and auto-shutoff nozzle. Its 47-gallon capacity is the boundary for longer supply runs.

#9

9. RDS 60-Gallon Toolbox Combo

• Dimensions: 55 x 20 x 23 in
• Weight: 110 lb

Best for: Toolbox-Top Diesel Transfer Combo.

Why it ranks #9: This 60-gallon aluminum tank combines a transfer tank and storage box, with fully welded seams and heavy-duty mounting brackets.

A storage box sits atop this 60-gallon aluminum transfer tank, combining pickup-bed fuel carrying with a place to stow gear. The listing also specifies an 8 GPM pump, fully welded seams, heavy-duty aluminum mounting brackets, and a spin collar for easier pump installation, making it a combined storage-and-refueling setup.

RDS specifies this tank for transferring diesel and other nonflammable liquids from a pickup bed to remote or heavy equipment. The 60-gallon capacity supports a useful onboard supply, while the toolbox above the tank adds storage without describing a separate bed unit. Fully welded seams and heavy-duty aluminum mounting brackets support the assembly, and the spin collar eases pump installation. Buyers should note that diesel installation kits are available separately rather than included in the supplied details.

Skip it if you want a simpler aluminum tank without a toolbox combo; RDS 71083 lists a 45-gallon rectangular auxiliary/transfer tank.

This combo suits pickup owners carrying diesel to remote equipment who also need onboard storage. The toolbox-over-tank layout and 55-by-20-by-23-inch dimensions deserve consideration when planning bed access and available space.

#10

10. Better Built 29211676 Tank

• Dimensions: 45 x 220 x 29 in
• Weight: 212 lb

Best for: Vehicle-Specific Better Built Listing.

Why it ranks #10: The listing identifies it as a Better Built transfer tank but supplies no capacity, material, or usable tank features, making pickup suitability difficult to assess.

The listing identifies this Better Built item as a Kwikee Series 42 transfer tank and states that it is designed to fit specific vehicles. That vehicle-specific focus is the clearest differentiator supplied, so buyers should treat fitment as central rather than assume a general-purpose pickup-bed match.

Unlike listings that specify capacity, material, or transfer hardware, the supplied information here gives the Kwikee Series 42 name and a vehicle-specific fit note. It provides no tank capacity or construction details to guide volume or material comparisons. The listed product dimensions are 45 by 220 by 29 inches and the item weight is 212 pounds, figures buyers should scrutinize for applicability before making installation plans. The sparse specifications limit assessment of refueling workflow.

Skip it if you need a stated capacity and material before choosing; Better Built 29211584 lists 36 gallons and alloy steel.

This listing may suit a buyer whose vehicle matches the stated Kwikee Series 42 fitment. Because capacity, material, and pump details are not supplied, it is difficult to assess volume or transfer workflow from these facts alone.
