If the bunk door is delaminating, I canít envision the problem being the fault of bad door seal, or poorly installed door seal. Those black foam rubber seals around the perimeter of door opening are meant to keep the water from getting inside the camper.
When the outside/bottom of the bunk door core (made up of a layer fiberglass, Styrofoam & vinyl back luan board) begins to swell up or budge, it is delaminating. Often the inside/bottom area of the vinyl backed luan will also become soft and damp, you may even see some staples in this area along the edge beginning to rust too. This is caused by water getting past the frame thatís wrapped around bunk door core. The sides/edges of the core are encased in the frame, but if water sneaks inside, it will be absorbed into the core.
Hereís a photo of the front bunk door on our í08 Roo, your 2010 is a little different, but the frame surrounding the core is much the same. If you look at the lower horizontal section of the core frame (not framework with the screw showing), you will notice thatís there is some caulking applied to seal the area between upper edge of the core frame and the fiberglass layer of the core. If the caulking isnít done correctly, water can sneak in, get trapped inside and start the delaminating process. Youíll notice that the caulking is applied around the whole perimeter of the core frame, but it is most important that the lower horizontal section and joint to either side is sealed quite well (the photo is not a good example). Because the front bunk door slopes backward with the camper, water tends to collect and sit in this caulked area. If you notice water sitting between frame and fiberglass panel after itís rained, itíd probably be best to apply a least one additional application of caulking to build up this area to shed the water away.
