I'm here to eat crow.
Many here have read my posts about the slide on our 2010 2551S and the fact that it leaves gouges in the vinyl in front of the fridge and a deep discolored indentation in the carpet in front of the couch. And then there were the wood bits coming out from under the fridge when we opened the slide. And then there were the scratch marks on the wall next to the fridge that were visible when we opened the slide. Ok, after talking to Kermit we took the motor home to a highly rated independent shop in Albuquerque and they went over the thing and pronounced it one of the quote best slides unquote they had ever seen and they have seen a lot of slides. The wood bits under the fridge were from a contractor type pencil under there being chewed up every time we opened the slide. The scratches on the wall are because that very thin piece of material bows. The indentations are the cost of doing business with the slide roller. There will be some minor mods I will now make that I learned from Bob Andersen and then no more on the the slide!
