Well, I took the trailer into the dealer and they inspected the wall.
They said that there is NO water damage and that the wall was cut too long at the factory.
So, they disassembled the dinette seat and trimmed the bottom of the wall a quarter inch. NO CHARGE!!!
They said it was out of warranty but decided they weren't going to charge me.
Gotta love United RV in Las Cruces, NM
