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 there they needed to fill. Over the years I've had a leak problem at the seal and I've added more caulking to it. My motorhome has spent most of it's life indoors so I only see the leak when I'm using it and it rains or when I've washed it, so hopefully not too much damage has been done.
I decided to get up there yesterday and remove all the old caulking and then redo the seam with Eternabond tape. Once I got a lot of the caulking off, I noticed that the gap is bigger than I would have thought. Basically the roof and the front cap come together and on the left side the roof has a slight dip to it. So the roof at the bottom of the dip, is close to a half inch below the front the cap. I can stick my finger in the gap. There is a painted metal trim piece over the top of the seam that is screwed into the roof. The trim piece sits flush on the front cap, but it is up to almost a half inch (maybe a third of an inch) above the roof. I'm pretty sure this dip in the roof had been there since assembly and they just filled it in with extra caulking because I've seen that since the beginning. So it's not the structure or anything under it giving way.
So the question, I'm wondering how to fix it. Ideally I'd like to get the dip out of the roof, but that is not a do it yourself project and I don't even know if a RV body shop could do that. So I'm contemplating other fix ideas. I'm thinking about removing the trim piece so I can completely see the seam between the two pieces. And then filling in any gaps somehow with the trim piece off, and then putting it back on re-caulk and then put the Eternabond over the top and double or triple it up in that area? It's pretty obvious that when they assembled the motorhome they fitted the fiberglass pieces and then put the trim piece on without any caulking underneath it and then caulked the joints as the last step. So I'm thinking if I get it good and sealed underneath that I can make sure it doesn't leak again.
Anybody got any better ideas?
