I have a similar issue with a Wildcat eXtralite 295RSX which I've never brought home. We spent 1 night in the trailer on the dealership lot to shake it down. We found a gouge on the wood-look flooring about 1 ft. in front of the left end of the entertainment center/ kitchen slide. The dealership had their own flooring man come in and fix it a gouge at a time. I saw the fix yesterday and it passed my scrutiny although Mama hasn't seen it yet!
I have a worse issue than an extra piece of metal hanging under the slide. My slide appears to be out-of-square on the leftmost inside corner. The slide comes in easy... but going out is a problem since it appears the out-of-square corner is too tall for the hole in the outside wall of the trailer. That causes the top of that corner to bind and, because the drive system is at the bottom of the slide, the bottom of that corner to drop and gouge the floor. I don't see how this problem can be fixed and the dealership service people have had no success in contacting factory personnel.
