1979 Trillium 1300 Restoration Project (Trillium's are similar to other small fiberglass RV camper trailers such as Scamp, Casita, Boler, Happier Camper, etc)

It's said that Trillium's were born with a brith defect: the belly band. It was attached by embedding a custom bolt (for lack of a better term) that was then riveted to the belly band. Problem is, the band area would leak over time, causing the bolts to rust and swell. The best fix is to remove them, and then fiberglass the gap.

In this video, I show the removal of the bolts.
