Yes, I ripped out the ceiling on our '73 and regret doing so as it was in good shape and irreplaceable.
FYI, the worst areas were behind the plastic panels at the cockpit, hallway, and rear ceilings and walls.
In all those places, the original insulation was either a foam or fiber material that had degraded badly.
Everywhere else had sprayed foam which, while it could have been better applied, was holding up fine.
If I were doing it again, I'd leave the original ceiling in place and only pull the plastic
areas for cleaning, repairing, painting and insulating. While the original spray foam application wasn't
great, I'd say the overall quality of the job was better than in our '75 coach.
I've found the rear interior cap the most difficult to deal with. The top corners
fit snugly and it's hard to get much insulation behind them. It's also an unwieldy somewhat
fragile piece. I removed it from the coach by passing it out the side windows.
It's a two person operation to reinstall.

Karen,
Since I plan on installing vinyl type material over the main panel, I am
thinking of gently fastening it in a few places and possibly using some
caned foam by drilling a few holes here and there just big enough for the
spray can tube to go through. I found some canned foam that expands but will
stop expanding when it comes in contact with other surfaces, unlike other
foams it will not become brittle, it is white and stays soft. I will have to
experiment with that before I try it on the MH.
I appreciate your response on the ceiling panel, I had a big diesel pusher
that they had upholstered the ceiling and the panels underneath were 4 X 10
and every 4 feet the material would create a crease, due to shrinkage and
expansion of the wood or plastic panels, depending how the weather was
depended how bad the seam looked. Since this panel is so big and I don't
want strips on my ceiling, I am trying to preserve it any way I can.
