Hey Bluwtr49!
Good idea. :) It used to show up in my signature line, but not anymore it seems.
Anyway... 1986 Triple E Invitation, 30' long, running a 454 big block (according to my uncle). Not a lot of miles on it for the age... I think it's sitting at less than 100k still. Single rear axle. Had some H2O damage in a previous life, but we resealed the leaky seams, and there's been nothing since. I'm *pretty sure* that the exterior skin is made of Filon... it's a thin, flexible sheet with a pebbly appearance & has what looks to be fibreglass fibres running through it.
Does that help at all?
