Does anyone out there own a Frontier by KZ with the rear slide out? If so please let me know if you are having problems with this slide...Mine keeps falling out of the ceiling during travel. It has been repaired over and over and still keeps falling down. I'm at the end of my rope with this unit and am ready to get a lawyer about the matter. It is a total lemon! KZ has admitted to this being a big problem for them and they are working on a fix...meanwhile I keep paying a note on a camper I can't use!! Please let me know if anyone else is having these problems!
