question about trailer construction
I have a question about trailer construction: The Hi LO I just bought is a 1994 Towlite 184 DL. The entire outside skin is aluminum. The inside of the walls appear to be wall paper over underlayment. Other then maybe insulation, what's between the 1/4" underlayment they use on the walls and the outside aluminum skin? Also, there is white foam board on the ceiling with joints every so often. What is between the foam on the ceiling and the outside aluminum skin on the roof? I am super curious. Being very particular about how things work and should work, I am wanting to strip this trailer down to four walls, re-seal anything that needs it, clean everything and make sure everything is working the way it is suppose to. I hate surprises and being an industrial maint. mechanic, not only do I do preventive maint, I also do predictive maint. This assures little to no breakdowns.
