AT105WX Auxiliary Fuel Tanks

AT105WX, the aluminum105 gallon auxiliary tank is designed for hauler beds or flat beds only. The AT105WX is the largest extreme wedge we manufacture. The AT105WX comes standard with duel fuel fill necks for faster and easier fuel stops. Extreme wedge tanks allow you to see your gooseneck ball or 5th wheel without the auxiliary tank interfering with your view. It also allows better trailer clearance with towing a trailer compared to a rectangular tank.
