I was toying with the idea of having TWO gas tanks under the bed just behind the cab. One would get the filler neck that comes out the stock location, and the other I would have to find a place to put the neck. Each would have a float in the tank, and an electric solenoid to switch between tank 1 or tank 2 would also switch which tank the fuel gauge would be reading.
It just seems that the stock 14 gallon tank under my ars just doesn't go very far on a tankful. I'd really like to have a lot more range, with a reserve tank.
