Gents,
As has been noted, many Jeep owners, that use them anyway, have done just what's been suggested. We've owned 7 Jeep Wranglers. (1) CJ-5, (2) CJ-7s, (2)YJs, and (2)TJs. All of them I installed engine driven air compressors. On two, I installed air tanks. One of which, was the front bumper. It was a 2"x4" tubular bumper with sealed ends and fittings on the inside(toward radiator). It worked flawless.
As many of you know, having compressed air at the grab of a hat, is priceless sometimes. But, in setting something like that up, it takes ingenuity, and tenacity. About 99.9% of the Diesel owners out there already have an advantage. They've got an engine driven compressor already on board. Many have plumbed and valved systems for airing up tires etc. already done by the factory.
But, the gas owners, well, that's where the ingenuity comes in. While it is possible, on some of the gas engines out there to rig an engine driven compressor, it is for the most part, a serious effort. And, the problem is, unless your air system, tank, lines, valves etc. are seriously SEALED, you won't have available immediate air, unless you start up your rig. That's not the end of the world, unless it's in the wee hours of the morning or late at night.
Now, we come to alternate ways of "making compressed air". I've built home air compressors and, even jeep compressors out of "Tecumseh" A/C pumps, and, Sanden A/C pumps. One is a piston style pump and one is a rotary style pump. The Sandon one is by far easier to mount up and adapt to surroundings. Then, all one needs is a 110VAC motor, a pulley or two, some plumbing and a tank.
Now if you've got a regular air compressor (compressor head) then, you still need the rest of the parts to build your system.
Then, you could simply mount, an already made unit, and plumb it to a tank via some lines etc. and put a couple of outlets, maybe one at lateral ends of the coach. You could have setup for it to come on automatically as you use air, or, have to turn on a switch to energize it. If our Itasca Horizon 36GD with the 330 CAT didn't already have an air system on it, I might have one built by now. As is, I still carry a Sears unit that's very popular on this forum.
