Thor Super C (Chateau/Four Winds) improvements and mods

I have been over 65 a lot (especially with the new shocks) and hear nothing like that. I wonder how many dealers put the slide out without the jacks down for dealer inspections, cleaning, etc. (before final delivery to the customer)? The slide is one of the weakest points on this coach. I take great care when putting the slide in and out (holding the bottom 2-3 seconds after motor turns off during each in and out...as described in book). I hope the design will last long term.
