RV Repair: Replace Insulation in old camper, ceiling insulation, spray glue

Question
I have a 1969 self-contained unit. Damage from mice has occurred in the ceiling and walls. I've been told that the mice ate the insulation. How can I replace the insulation in this camper? Other than the insulation problem, everythiing else in the camper is tip top shape! I'd appreciate any advice you can give! Thanks.

Answer
The paneling on the inside (roof and sidewalls) will need to be removed. Then you can re-insulate. You will probably have to hold the ceiling insulation in with tape until you repanel it. The sidewall insulation can be held up with spray glue. Don't try to insulate from the outside. That would be very difficult to remove the siding and roof. It is not easy to do it from the inside either, but much easier than from the outside.
