Most factory customer service centers have "campgrounds" where you can stay at no cost. At Fleetwood in Decatur, IL, you just pull into this big gravel parking lot the night before and choose an empty spot. You plug in and spend the night, along with everyone else who is getting stuff fixed the next day. They also have a dump station and potable water supply.
The first time, they fixed everything in two days. The best part was that they issue you a pair of safety goggles and allow you to stay in your vehicle while they work on it, assuming they aren't tearing up the floor or something. They keep you plugged in while they are working on you. So the first time, I sat in my recliner and did work on the internet. I think I also watched local TV. At night, they pulled it out and plugged me into power again.
Second time (six months later) I had to go in was to get a soft spot fixed on my floor, so they had to keep it torn apart for 10 days. I rented a car and drove to my son's house where I stayed until it was all fixed. If it had not been under warranty, it would have been a $20,000 bill because they had to tear out the floor including the subfloor--right down to the metal frame. Turned out it was a broken weld on the frame, so I got a new subfloor and new linoleum. Worst part was having to pack up my kitchen since they had to remove my kitchen slide and sofa. Since I was leaving it, I also had to pack up all my valuables and electronics and take them with me in the rental car. I did leave food in the refrig since it was plugged in while in the shop.
But, they had all the parts there and fixed everything right the first time.
Actually, the second set of fixes was after the warranty had expired, but it was all covered because I had contacted them before the warranty expired. I had noticed the soft floor while I was down in Florida and had taken photos and taken it into a dealer they recommended to verify the problems. Because the work was so complex and involved removing the heavy slides and the flooring, the dealer could not handle it, hence the trip to the factory.
