We have owned our 2008 Windsport for 3 years. Its the 36F Floor plan, really nice economic Class A with great options. We bought it at the RV and Boat Dealer just west of Knoxville, TN. When we looked at it on the lot, a used unit with very low mileage and little wear, both slides were out. I asked to have the slides brought in so I could see the room while on the road. The larger slide in the dining room/bedroom side would not come in. We were told not a problem we will make everything is right before releasing to you. When we got back to pick up the unit, I asked to speak to the repair person who looked at the slide to see what was done. Well, nothing was the answer. When he pushed the button the slide came in. He pushed the open/close several times without a problem. We drove the unit home (150 miles) parked in our driveway, opened all slides to pack it for a trip, when we tried to pull in the slides and the same one would not come in. Finally after several button pushes it came in. This was a problem through out the next 3 years. We got stuck in Michigan, South Dakota and Florida. Each time we took it in for repair, after too many $s to mention, we finally took it to Maxey Cullum RV in Nashville, TN. Finally a technician took the time to trace down the problem and I want to share it with everyone - just in case this might be your problem and no ones knows what to do. SOLUTION: There is a fail safe button on the wall hidden behind the door in the hallway that goes into the bedroom - across from hallway closet - that wasn't hitting the door when it was shut. This door must be locked against the wall when the slide is in because the slide closes the hallway completely and the door would be crushed if not secured. The technician replaced this button and aligned it to the wall in order that the door hits it now. No one - not even the Thor or Four Winds technicians even knew this was there - it is not on the master blueprint for this unit. But thank goodness someone took the time to keep looking and not just assume nothing was wrong. We had even changed wiring in the control panel thinking it was an electrical shortage - the other slide always came in but this one was unreliable. If you have this problem - look for a button on the wall (floor level) behind the hallway door in the bedroom.
But we are upgrading to a diesel today - but whoever gets this coach at the Tennessee RV dealer in Knoxville can rest assure - everything works perfectly now.
