Solera Slide out sleeve

I just spoke with mobile outfitters today. The sleeve has been halted with technical problems but I got the impression that the topper is still available. Apparently the issue is interference with the seals. Specifically those applications where the bulb seal is on the wall of the RV and not the slideout. I spoke with two people and neither gave me a warm fuzzy about the product. Too bad as it is a good idea. I may make my own.
