What can be done to eliminate the gap being caused between the part of the upper portion of the shower wall and where it overlaps the lower portion of the wall. On one wall the portions overlap with no gap and on the other wall the upper portion is bowed out and creates a gap of 1/2 inch or so between where the upper portion overlaps the lower portion. I believe I've read posts that state that the two parts overlap and that it should not have any leakage problems, but it doesn't look very good.
I have repaired mine but it involved taking the shower stall apart. After that was done, I adjusted the "bow" and used screws with buttons and sealer to tighten it to the wall. You may be able to just flatten the upper portion and re-install the shower frame to hold it in place. I also used shower/tub glue and silicone caulked the top. (be sure the glue is compatible with your shower panels)Hope this gives you a couple of ideas. VK
Thanks for the ideas. They will be helpful when discussing what needs to be done with the dealer. The trailer is still under warranty and I'll see what the dealer suggests doing before attempting any repairs on my own.
