I was an IDIOT for buying a Thor Palazzo!!!

If that last pic is a slide its probably the wood wrapping to make the particle board look like real wood. The slide probably dragged and due to it not being wrapped correctly pulled off. I had our MH in for the same thing ( not wrapped correctly). Just plain lazy work and lack of quality control.

The slides ... I feel your pain !! Make sure you start documenting all your repairs. They might come in handy down the line.

Quick question, was the motor home level with jacks down when this happened.
