Since the day we bought our rig in Dec of 2011 we have had a leak coming down the wall inside the front and rear of the bedroom slide when it's raining outside. Our dealer has been more than willing to take it in and try and fix it, but it's still in the shop after 4 attemps and 6 months. Now they think they have the answer. The maker of the slide mechanism has said they need to remove the cables that open and close the slideout, heat the cables and apply a wax the maker of the slide will provide. They think it is traveling back in on the cables. They have tried various remedies. Caulked the seams on the outside of the slide, claulked behind the rubber sealers on the inside, built and installed little aluminum rain diverters under the opening of the slide on each corner down where the rollers are. I want to know if the factory uses this wax when they install the slides or are the cables supposed to impregnated with this wax when they get them, or are they just grasping for straws. I am so frustrated, I wish there was a lemon law for 5th wheels. We have used this rig a total of maybe 20 days since we bought it new.
