Seems to be where everyone puts em. They'll fit there nicely. If I were doing it I'd make a cutout in the bumper behind the license plate and put a '70s flip down plate holder to cover the filler.

Other than towing I probably wouldn't keep much fuel behind the rear axle. It may have a tendency to make it waddle.

This is a BIG project. Not for the faint hearted. The wiring alone would take me around 7-9 hours and this is a fairly simple wiring job. 1 power wire to the fuse panel on a circuit that's energized in Start and Run. Six wires exit the cab. 2 valve energizers. 3 senders to the tanks. 1 fuel gauge wire to the main bulkhead plug. Ground straps at each tank.
Some Fab work at the rear for the tank hangers and filler neck.
Fuel feed and return line including new, modifications, and outright replacements.
