RDS Auxiliary Tanks
Auxiliary Fuel Tank & Toolbox Combos with Fuel Filler Shroud
Increase driving range with an auxiliary fuel tank with toolbox built in! Auxiliary tanks can be used as additional capacity for a factory tank with the use of an RDS diesel install kit. Shop for better fuel prices with this increased range.
Each tank comes with gas cap, drain fittings, manual sight gauge, fuel filler shroud, along with internal baffles to reduce sloshing. Toolboxes come with linked stainless steel locks that also secure the fuel fill to prevent tampering, and two lift cylinders to hold open the crowned lid. All tanks Meet DOT standards.
