My thought was to install nailers crosswise to each loop and then find fiberglass panels for a more commercial look for the ceiling. (After sprayfoamimg of course).
Just an idea
Might be different for your bus, but when we made 5mm plywood ceiling panels for our International/Amtran bus, it came out to less than 8 feet. The sheets came in standard 4'x8' size and we ended up cutting several inches (6, maybe 8?) off the end of each. Our bus has a beveled panel where the ceiling and walls meet that houses the lights and some speakers....so this eats up some of that room. If you're removing those panels anyways, though, it could very well be right around 8'. My advice, always, is to measure twice before buying any materials or equipment you plan on putting in your build.
