We put these vehicles through low level hurricane force winds as we drive them down the highway at 60 to 70 mph's, so I always look at the seams and trim at least once a year to make sure nothing is opening up, as I clean and polish my unit.
On then roof, I have used Enduro tape over all the caulked edges and seams.
White on the roof surface around the vents and satellite connections and then black around the exterior trim cap to match the color and not standout where it can be seen from the ground. I've done this on 2 trailers before this coach and very satisfied with the results.
Doing my annual cleaning and inspection and have noticed a couple of places where exterior trim molding seams have a gap or crack in sealant along the trim molding. In the past any open seam have been filled with a silicone caulking. In cleaning above the cab I noticed the edge of the trim coming loose. Sealed with caulking, but wondered if anyone has used a screw through the molding for a better mechanical attachment? I just can't seem to get this trim to snap back in place or stay tight on this horizontal surface, so just filled the seam with caulk, but looking for other ideas.
Thanks in advance for any ideas.
