Re: Auxilliary gas tank
A pump would be pretty slow to transfer. I've looked at it some more and think I could run a filler hose from the back, maybe above the stock filler. With a good vent hose it should fill pretty well.
Lots of pickup trucks use an electric valve that switches from tank to tank, and switches the gauge at the same time. The real question right now is whether somebody makes a tank, or if I have to make it myself.
There's a lot of room there; I think it would be easy to get about 7 gallons in, and more if I want to drop below the frame rails, which should be OK since the skidplate, driveshaft and differential are down there.
Keep the ideas coming. Especially if it's never been done before.
