We just came back from a 2 1/2 week out East trip with our 2014 Coachman Clipper. During the trip, the aluminum angle by the door the screws came out, upon removing the angle I saw water leakage under the flooring. We don't use the shower/toilet ever, so it's gotta be outside water getting in. I am drying it out now, then will re-install the aluminum angle with a few more screws. I looked under the floor and looks like the black covering is properly attached and not tears or openings at edges My best guess is the water is getting in via the lower black angles, there's no clear caulk there like on the door seams. Heck, I could easily put my fingernail behind the angle and see into the box, so definitely it's a water path. I'm going to clean that area and put outside clear caulk on the angle edges as shown via my RED markup at the base of the box. Questions: Has anyone else seen similar water damage like this? Has anyone else caulked their lower box bed angles like I plan on doing?
