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.
