Bhbldr, our 5er went back to the factory last December or Jan for the dining slide floor. You could feel what seemed like a seam that was giving way. They replaced the floor in the slide and all was well from there. Later the main floor started to drop about sixes inches from the wall on the dinind slide side. We took it back to the factory ourselves to have the work done. They lifted the "box" and completely replaced the floor. Amazing what they can do. I asked for a couple of minor things to be looked at knowing I am out of warranty. They took care of all the issues I had and the couple of added things I wanted done and didn't charge a penny for the extra work.
I have not been lucky in regards to problems with this unit but none of them have stopped us from using it and the customer service from Rockwood/Flagstaff has been outstanding.
I don't know if the rest of the FR family is this good but I would not hesitate to buy another Rockwood simply because of the support after the purchase.
At this point I am happy to report that after four nights on the road and about 1300 miles everything seems to be great with the unit.
