I am working on getting my 75 ready for a trip to Alaska this summer. Just installed an Atwood 8500 heater where the old non forced air heater was located., As I was making this modification I realized there is no insulation in the bottom half of the Alaskan. Does any one know if there was insulation installed in the ceiling or top half of Alaskans in this time period? I can cut foam board to insulate the bottom half but am not ready to start pulling paneling off the top half. If there is no insulation in the ceiling or top half, do you think I cut spray foam insulation in between the roof supports? Seems like it would take allot of holes.
Thanks.
Thanks.
