All the dealer mentioned was a few mirrors cracking in the bathroom, and I believe he said something about cabinets in the kitchen area. He didn't go into a lot of detail, and I don't recall him saying anything about the frame/ chassis. I hope he was only refering to the insides of the coach. The radio that came preinstalled with our unit, a sanyo, was useless, cd player wouldn't work. The dealer did reimburse us $200 towards a new one which we had installed on our own. I know what you mean about the floor mats. Right now we're using carpet scraps cut to fit.
Apparently trail-lite disregards any mail sent to them, and it seems they don't want to be bothered by e-mail. The only way for contact is by phone.
