I have an MCI-8 and wondered how thick is the celiing material? How do walls or shelves usually get mounted?
If it's stock there is a 16 gauge aluminum ceiling, about 1.5" of fiberglass matt, then a roof of about .100" aluminum. The ceiling is not particularly structural but the roof definitely is. There are steel ribs in behind the rivets.

it seems that the first layer from the inside is plastic...
My bus, 1980 MC-5C, the ceiling material is the thin aluminium but it does have a plastic coating.

Most people, when doing an interior of a coach, pull out the original ceiling material to better insulate the vehicle (best is spray foam).
In so doing, the structural ribs are exposed, thus allowing you access to points significantly strong enough to hang cabinets, secure walls, run electrical, etc.
The same applies when you pull the original wall panels, too.
FWIW & HTH. . .

I stripped my interior all the way down. It exposed two cracks above each door-not a surprise being a transit bus with hundreds of openings and closings a day. I welded up the cracks, steel brushed everything then primed it all with Rustoleum. I then installed 1x2 fir strips to be able to anchor the roof and walls to. I also installed a 1x3 doug fir strip to support my overhead cabinets (they're still up after nearly 40,000 miles of driving). I then had American Foam come in and spray foam everything to have 2.25" of insulation. Then covered the ceiling with 1/8" plywood (it conformed to the curve of the ceiling) and 1/4" plywood over the walls. Have always been pleased with the insulation-makes for easy cooling and heating. I was just came down from Mammoth and it was 97 degrees out. I ran just the front and rear roof air and it was 72 degrees inside going down the road. Good Luck, TomC
I spent the extra time and money and did like tom by insulating between the frame, wrapping reflectix over the frame, additing furring strips and more insulation. You can read about the wall insulation here:http://www.herdofturtles.org/2012/08/27/new-walls-funny-math/ (http://www.herdofturtles.org/2012/08/27/new-walls-funny-math/)
Spend every penny on the most insulation you can put in. I can tell you now that I'm glad I did and it makes a big difference.
