I added a 42 gallon auxiliary tank between the frame rails on my '14 Power Wagon, its where the factory spare tire went originally. It has dual pumps and they are switch controlled. It was an experiment and needs a little refinement, but 70 gallons of basically invisible fuel on board is tough to beat. If I could have bought a drop in tank that held more I would have, it was a ton of work to get where I am now. On those long, way off the beaten path Nevada and AZ hunts its been well worth the effort.
