Yes, all the support mounting is vulnerable to leaks in all trailers, but some support is more vulnerable to rot than others. I contend that instead of two major construction types, there are 3.
1 Roof and side panels with an interior wood framing.
2 Molded fiberglass shell with an interior wood framing.
3. Molded fiberglass.
It appears to me that the only real difference between a Big Foot and a true sticky is Big Foot uses a molded fiberglass shell rather than panels. I agree that that is a big difference, but not as big as those with a lot less wood. Yes any wood is vulnerable to rot if moisture gets into it. But a moisture path is less likely when there's no direct path to exterior of the shell. Not all molded fiberglass trailers have a A/C so have even less wood. A window leak is not going to rot out part of the wall like one of our members experienced.
My whole point is when purchasing a trailer try to understand the whole ramifications of different styles, including construction. All molded fiberglass trailers are not the same.
It seems to me that you've got bit defensive on this issue. I by no means intended to insult either you or Mike's intelligence. You've owned enough trailers that you've made your choice abased the compromises that best suits your needs. I assume that Mike has also.
Nope, Byron... not defensive at all. And you're right... I've had enough of them to know the differences. I think there's a misconception about how the Bigfoot interior is constructed. It doesn't have a "wood frame". My point is that there is no "choice 3" per se... they all have interior supports, be the supports wood, wood products, or fiberglass, and all have some wood reinforcement somewhere
even if you can't see it. And when you can't
see it (as when it's glassed in for re-inforcement), it's even more vulnerable, and a much bigger job to repair.
The interior supports in a Bigfoot are the walls and cabinetry, just as in all the others. The choice of wall coverings (basically insulation covering) is different and employs wood furring strips to attach the paneling to and cover the insulation, but it isn't structural. The basic interior construction/support isn't any different in the 2500 series than Casita
or Scamp uses. The hull is the structural material, and it's held up by interior support walls. A factor that is perhaps further confusing the issue is that Bigfoot experienced problems with the flat roofs they used for years, and now have re-built their molds with shaped roofs for strength and for better water/snow/ice shedding. Some of the older Bigfoot trailers had a weak flat roof design with roofs that leaked around the vents over the years. In those, the wood used as furring strips was also structural, and the leaks
caused the furring to fail, and subsequently the roof to sag. That is largely an issue of the past.
My Born Free moho is
framed with wood with molded fiberglass panels and roof attached over them, and then the seams sealed. The wood is structural. That is a whole different construction method, and perhaps closer to how you may have thought the 2500 series Bigfoot trailers are built.
