Outdoor RV TT's: Schwintek vs. Rack & Pinion Slides

I have Schwintek dual motor rack system on my Grand Design and I will tell you I've had problems with the slide from day one and its only 1 year old. Had the slide adjusted twice, a motor replaced on one side and now Schwintek (Lippert) is replacing both motors, and the rack and block system.

I don't know if the trailer you are looking at has 2 motors for the slide, but I would advise against buying that one. Of the 6 or 7 trailers we have owned, I have never had a problem unit until this trailer.
