The best 80-gallon transfer tank depends on your truck-bed layout, preferred tank material, and fuel-transfer needs. The RDS 71792 is a straightforward aluminum option with listed dimensions, while the Dee Zee DZ92556B is better suited to buyers who need fifth-wheel trailer clearance. The RDS 71793 is a fit for shoppers who want listed fuel-type details, and the other RDS model offers a second rectangular-tank option. One listed Dee Zee model holds 106 gallons, so it is an alternative only if you do not need an 80-gallon capacity.

RDS 71792 Rectangular Aluminum Tank
The RDS 71792 is an 80-gallon rectangular transfer fuel tank with a silver mill-finish aluminum exterior. Its listed dimensions are 50 inches long, 20 inches wide, and 19 inches high, making those measurements useful for an initial truck-bed fit check. The product listing identifies it as an auto accessory and states that it is made in the United States.
Best for: Buyers who want a listed 80-gallon capacity, a rectangular profile, and clear external dimensions to compare with available bed space. It was selected because its capacity and size are specified directly in the product name.
Consideration: The provided features do not describe a transfer pump, fittings, or installation hardware. Confirm what is included and check the required installation details before choosing it.
Dee Zee DZ92556B Brite-Tread Tank
The Dee Zee DZ92556B is described as a non-rusting tank made from .125 Brite-Tread aluminum. Its listing also highlights clearance for fifth-wheel trailers and a radius curve intended to eliminate weld pressure points. These construction and shape details make it distinct from the RDS models whose supplied descriptions focus mainly on capacity and dimensions.
Best for: Buyers who need to consider fifth-wheel trailer clearance and prefer an aluminum tank. The stated clearance feature is the clearest reason to compare this option with a conventional rectangular design.
Consideration: The provided product details do not state the tank’s capacity or dimensions. Verify both before purchasing if an exact 80-gallon capacity or a specific bed fit is essential.
RDS 80-Gallon Rectangular Auxiliary Tank
This RDS model is identified as a rectangular auxiliary transfer fuel tank with an 80-gallon capacity. Its listing states that it is made in the United States and provides package dimensions of 127.0 cm high, 48.26 cm long, and 50.8 cm wide. The listed package weight is 48.081 kg; package measurements may not be identical to installed product measurements.
Best for: Buyers comparing 80-gallon rectangular RDS options who value the stated country of origin and want package measurements for planning. It adds another capacity-matched choice alongside the RDS 71792.
Consideration: The supplied features do not identify the tank material or describe fuel compatibility. Check the full product specifications for those details before deciding.
Dee Zee DZ91753SB Black Steel Tank
This Dee Zee tank is a 106-gallon rectangular transfer tank, not an 80-gallon model. It is made from heavy-duty 14-gauge steel and has a textured black powder-coat finish described as helping increase corrosion protection. The listing also notes a radius curve designed to eliminate weld pressure points.
Best for: Buyers who want a larger-capacity steel alternative and have confirmed that their vehicle and fuel-storage plans can accommodate 106 gallons. It is included as a clearly labeled alternative for shoppers whose capacity requirement is flexible.
Consideration: Avoid this option if 80 gallons is a firm limit. Its listed 106-gallon capacity differs substantially from the requested size.
RDS 71793 Fuel-Type Option
The RDS 71793 is listed as an 80-gallon rectangular auxiliary or transfer fuel tank, with dimensions of 50 inches long, 20 inches wide, and 19 inches high in its product name. The supplied details say it can transport diesel fuel, gasoline, or aviation fuel, and can gravity-feed diesel only.
Best for: Buyers who want listed information about fuel types and a diesel-only gravity-feed capability. Those details help distinguish it from listings that do not specify fuel compatibility in the supplied features.
Consideration: Gravity feeding is specified for diesel only. Do not assume the same transfer method applies to gasoline or aviation fuel; confirm the complete product instructions and requirements.
Buying Guide: How To Choose An 80-Gallon Transfer Tank
Will the tank fit your truck bed?
Compare the tank’s length, width, and height with the usable bed area and any existing equipment. The RDS 71792 and 71793 list dimensions of 50 x 20 x 19 inches. For the other models, confirm product dimensions before purchase. Allow for access to the filler and any equipment you plan to use.
Do you need exactly 80 gallons?
Check the stated capacity rather than relying on a general product category. Four listings here identify an 80-gallon tank, while the Dee Zee DZ91753SB is listed at 106 gallons. Choose the larger model only if that capacity suits your requirements and available space.
Which material and shape matter?
The RDS 71792 is described as silver mill-finish aluminum, the Dee Zee DZ92556B as .125 Brite-Tread aluminum, and the 106-gallon Dee Zee as 14-gauge steel with a textured powder-coat finish. The supplied details do not specify material for every model. Compare material, exterior finish, and tank shape using the full specifications.
What fuel and transfer method do you need?
The RDS 71793 listing names diesel, gasoline, and aviation fuel as transport options, but specifies gravity feed for diesel only. Do not extend that feature to other fuels. Check the complete manufacturer information for intended use, included components, and installation requirements.
