Cab over rot

Considering buying a brand new class C

Have been looking at used class C's for a while now and virtually everyone has some degree of rot or delamination in the cab over portion. Is it inevitable due to design or does everyone just suck at maintaining them?

I'd say the latter. I bet 90%+ of owners don't have a clue about seal maintenance.

When the roof leaks on your house, you get a new roof. When the seals leak on an RV, it's already too late because it's rotten underneath.

There are plenty of well maintained used Class C's for sale that have no cabover problems. Maybe you selecting Class C's that are deeply discounted?

I don't believe it is inevitable, although the ones with window in the cabover seem to have more problems than those without, but any of them can have leaks, unfortunately you may not notice them right away, which creates a worse problem.
Maintenance may not be a matter of neglect or poor maintenance, I resealed mine before we left on a cross country trip, a 4 month trip, before we got home, I had a serious leak at the front seam.
