Been RV'ing for 20 years now, 6 of those years were full time. 6 class A buses, 2-5th wheels and a class B. Three have been new, high end coaches with multiple slides. All but the high end 5th wheel were basically junk. Slides leaked on all of them or did not work properly. I've met a lot of people on the road, and I can tell you that the majority of them have had slide problems. I finally got so fed up with it , that I sold my last new unit, a 2012 model with 4 slides, and bought a 1989 Bluebird Wanderlodge with no slides. I should have done this many years ago. It would have saved a lot of aggravation. Slides are nice, as they give you a lot more room, but most people don't spend much time in the rig when they are parked anyway. I would never have a unit with a slide again.
