Aluminum sides are easier to repair if the wall is damaged. Fiberglass suffers from Delamination...always...every fiberglass camper will eventually delaminate to some degree or another.
Every fiberglass/Filon sided RV I have seen uses square aluminum tubing for "studs" and solid foam insulation.
Aluminum sided RVs usually use wood studs and fiberglass insulation.
I would expect that the fiberglass/aluminum/foam would weigh less, but i have heard is actually weighs more :h
I think a lot of it has to do with how the RV is built. Aluminum rots in its own way so it's not perfect either. There are also some, at least there were, RV's that use aluminum studs and aluminum siding. So it reallly is a mixed bag. Some manufacturers use aluminum studs with wood trusses, or aluminum studs on the sides with wood trusses and wood framing on the front and rear of the camper. From what I have seen it's pretty rare to get 100% no wood in a RV build.
Foam can hold water too...some types of wall construction such as Azdel is impervious to water penetration...but that doesn't mean everything else in the RV is.
Thanks!
