B+ motorhomes
I just bought a Trail Lite B+ 211s with 8.1 Chevy engine. This is my fifth motorhome (others range from an old 20' Vagabond, and three Winnegagos, from 19 to 32'. This vehicle is fantastic. I am...

I found another thing, I hope it is only a problem on my coach and no one else's. There is a painted aluminum channel that makes the bottom edge on the exterior wall panels. Under the chassis, that channel is supposed to hold in place the black plastic sheeting that protects the inward sides of the wall panels where they hang down below the frame.
Underneath the sheeting is the same paneling you see inside the coach.
Well my assembler did not get the sheeting under the channel in quite a few spots. Resulting in a path for water to get into the wall panel when driving in the rain. For most of the problem areas, the sheet is still adhering to the paneling except for the bottom edge of the sheet, less than an inch. Nevertheless I have to seal it. The right way would be to remove the channels and reinstall them, but they are super tight.
Almost nothing adheres to polyethylene. That's why they make glue containers out of it. :) But since Dicor sticks to TPO and it is a close cousin to PE, I figured I would try it. I cleaned a spot and stuck a blob of the non-sag Dicor to it. Dicor stays soft for a long time but it did seem to stick very well. Today I cleaned up all the suspect areas with lacquer thinner and will seal them with the Dicor. If that doesn't hold up, there is a tape made for the poly under-RV sheeting. The tape is called Flex-Mend. Whether it sticks to metal, I dunno. I hope the Dicor holds.
I did a little bit of it today as a trial. The sheeting has taken a set with a curled up edge and kept pulling away from the dicor. I used masking tape to hold it down tight on the dicor and we will see how it goes.
One spot was really bad, the sheeting was able to pull completely away. This is the back driver's side corner in the following photo. The plywood was actually soft. I'm real glad I caught this before it got any worse.
