Gap between roof and front cap
When I first bought my motorhome (12 years ago) I noticed a lot of caulking on the left side of the seal between the one piece fiberglass roof and the front cap. It was obviously that there was a gap...

msmith the reason why MH mfg don't do a lot of things is for cost reasons. Caulk is a lot cheaper than 3M 5200. Is you main concern the difference in CTE( thermal expansion) and the roof pulling away from the front cap? Or the vibration while driving? Any mechanical fastener that you use, screws or bolts will restrain the cap and roof. If you have to replace the front cap or FG roof, which I have never heard of, there would be much bigger problems like a front end collision.
My reply to this earlier didn't seem to post? To answer your question, yes on thermal expansion mainly. As for if I have to replace them you're right, it would likely be from some type of physical damage and in reality that would be the insurance companies problem if they did have to replace both. And yeah, I understand the RV people wanting to save money, but since this front seam seems to be the main source of leaks in many RV's, you would think if gluing the two pieces together would fix that they would all be doing it. Do you know of any manufacturer who did glue them together? Have you done it yourself?
