The RV stores in my area usually stock primarily ProFlex RV, Dicor self-leveling lap sealant, and Dyco C-10.
The RV salesman recommend ProFlex RV for the sides and Dicor for the roof, but I decided to try ProFlex RV for all areas. He didn't seam too familiar with Trailmanors and had never heard of using a polyurethane caulk such as 3M 4200.
The contents of ProFlex RV are Tetrachloroethylene, Thermoplastic rubber, Plasticizer; and Thermoplastic Elasformer. Here are the tech data and the product specs:
