Not a bad thought, but a LOT of threaded connections to maintain and with a truck that flexes and moves and lots of thermal changed, the hard lines will leak. You don't want that on the trail.Here's a thought:
Divorce my puma from the tank and put it in a 2nd battery tray under the hood, controlled with a switch on the dash. Run hose from compressor to tank mounted under truck somewhere. From tank, 4-way manifold running out to each corner of the truck with a quick disconnect mounted to each bumper corner. Then 4 small straight sections of hose to run from the bumper corner to the tire.
Everything is hard mounted except the 4 small hose sections that go to each tire (36" lengths or something like that). Minimal stuff to pack up.
I'm sure something like this has been done. I'm just trying to find a good way to hard-mount my puma so I don't have to schlep it around anymore
I would consider it with hose, covered for high wear areas, but it must be well secured. Hoses made to length for each location.
Make sure to have valves near the distribution block for each line so you can isolate one line if necessary, especially if you depend on air for lockers.
