additional fuel tank
We just bought a F350, gas engine, where we'll put a camper on.
After exploring Canada and US with it, we want to continue travelling all the way towards the south. Maybe we will have to travel long distances without gas stations along the way.
Our truck has transfer case and fuel tank skid plates.
Is it possible to put an additional fuel tank below the truck ?
If yes, would it make sense to do the undercoating of the truck before (or after ?) putting the additional tank ?
Thanks for any advise !
