We have a '88 Ford B600 with almost the same setup. I you look at the "Big Mac" thread in the small school bus threads you'll see it. Eventually it'll be our son's home. We're planning to sheet metal in the front door and have steps going up the handicap door to give him more living space and a passenger seat where the entry steps currently are. There will be an access door below the passenger seat area for him to keep tools and whatnot. Go take a look at the thread it may help...
