Having a resource like Joe offer this kind of help is worth its weight in gold (literally!). If I still lived near Chicago, I'd be all over this offer like white on rice (even though I already have my Prevost). I'd give anything to be able to learn the "in's and out's" of my rig's systems and components from a pro like Joe (instead of the "trial & error" method newbies like me are so often left to employ).
You're a lucky man, Bob!
