My take as well:
Most trailers use a rubber roof that has to be caulked. Without frequent upkeep, the trailer will get water damage and fall apart. So, essentially this is a self destruct system in place no matter how good the owner maintains their trailer.
That's one of the best ways to put it that I've ever read.
In my experience, there are body seams that are even more trouble-prone than the roof. These are the seams which have the corner trim facing upward, either straight up or angled. The most obvious of these are at the bottom of the front room of a fiver, or the bottom of a cabover on a TC or traditional Class C.
But your point is right on. The average owner is just going to use the RV, and has no idea what to do to keep it leak free. And without very good maintenance, it will self destruct. Not to mention, all the decals and various plastic vents and hatches look like krap at the ten year mark. All in all, I'd say ten years and it's a beater, in most cases.
My motto: Buy at 3 years old, sell at 8.
