Just got my unit back. Took two days to get the repairs done. It looks like they decided to reinforce the existing walls, and resecure, rather than take the whole slide apart. Frankly, I am happy with that solution for reasons of alignment. They also reset the wheels at the bottom of the slide so there is constant contact with the floor, taking stress off the wall panels. It already rides quieter, with all the repairs done. BTW, I bought the Camping World extended warranty a few months ago, including the slide coverage - hence my lack of panic.
I am approaching the end of the year warranty, but overall, I am pretty confident that I can keep up with maintenance between the items still in warranty, the extended warranty, and my own inherent ability (to stick my fingers where they don't belong) to do some repairs.
