Trek shower design flaw?

[Rockyroad]

I just purchased a Monaco Trek( same configuration as the Fleetwood Flair.) The shower walls have two narrow diagonal walls on either side of the shower door. They are covered in wallpaper, not the acrylic ( or whatever it’s made of) shower wall assembly. Are they all made like this? I have a severe leaking problem and the shower needs to be taken apart and redone, fabricating two acrylic strips, etc.

PS- This is the 2016 model; only manufactured for one year.

I guess the wallpaper is "wicking" the moisture down the wall behind the caulk at the bottom? Looks like a poor design. I would cut a piece of acrylic or whatever and glue it over the wall paper (if you can't remove it) and caulk all the way around it with clear silicon caulk..

Yes, my rv tech is planning on adding these acrylic strips, tacking them under the shower door. Horrible design flaw!
