hi everybody! I recently bought a '79 gmc vandura coachmen conversion. my first van. no rust really so I want to keep it that way. the interior is wide open. walls and ceiling are beige upholstery and there is just a newer piece of beige carpet on the floor. it's all in nearly perfect shape, it's just boring! I plan to leave the ceiling as it has some sweet fake wood and the lights are fine, but would like to change the walls and floor. if you had a blank slate to start with, would you paint the floor with rhinoliner (or something like that)? should I fill in any holes on the floor with something? would you insulate the walls? is wool good, or would you use something else? I want to do it right the first time. thank you!
