ok, first the feedback you can use... whoever said one comp per 3 gal tank hit it on the head. it's gonna take way to long to fill a 5 gal tank with one compressor. i run my whole setup off a single 3 gal tank with 1 compressor. when the tank is full (160psi) i can fill my bags to ride height all the way around. Then it takes about 2-3 to refill the tank.
that seems to work well for the "just gonna drop it at the shows". I will also tell ya that for the first two - six months, you'll play with them at every stop light you can. at least i did. especially if the wife or kids were with
ok, the other thing for ya is a pick of my compressor, tank, gas tank and exhaust setup. i'm not sure if you can do this though since you're a step bed.
i'm not sure mounting it under your cab is gonna work. you may run the risk of laying your truck down on the tank, or it hitting bumps in the road.
you have to keep in mind that your truck MUST still move @ 10mph or so if you're completely aired out. if not, you're gonna be screwed if anything ever blows going down the interstate.
