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.
