My new TT, where are the trouble spots?

IMHO the two things that have the highest payoff in trailer protection against it's #1 enemy ... WATER are in the two links in my signature. As a third item I would completely redo all the exterior caulking where Eternabond is not feasible with a high quality adhesive/sealant like the 3M Marine 4000UV.

Some will question using the Eternabond on a new trailer as it relates to warranty, but IMO if you do the Eternabond properly warranty will never be needed. Two areas that needs particular attention are the four roof corners where the front/rear cap molding forms a right angle with the trim molding that runs up the front/sides and onto the roof. That area forms a "dam" where water will pool and eventually normal caulking will fail and you'll get a leak at that corner. The other are all the lights and any exposed screws including all those under the vinyl insert molding and my Eternabond link has IMO a couple of good methods/alternatives to effective seal those against any potential water intrusion.

Lastely I'm a firm believer in the RainKap system for two reasons, it effectively eliminates any black streak issues and it helps to prevent leaks from any fittings under it since the water will not normally run down the sides of the trailer.
