My '08 has a Lippert frame and slide. I have no issued with the slide (yet) but the worksmanship on the frame is atrocious, IMO. Spring hangers all out of whack and poor weld quality all over. Mine is rated for 10K GVW and is a full "I" beam, not welded fabricated "I" beam, so it at least has that going for it. The Plant manager of the facility I spoke with in regard to my unhappiness with their level of quality is NOT an RV owner. Told me so with his own mouth. Don't know if he's still there, but they have little regard for quality complaints AFAIK. All varying level of junk across the industry.
