I just needed to chime in on how happy I am with the Winnebago support. A month ago I crunched three basement doors on the passenger side of my '04 Horizon on a rock somebody placed too close to the edge of the corner. Roy Robinson in Marysville, WA. is doing the repair and was able to order the doors. One was in stock and the other two had to be fabricated. It's in the process of repair now.
Like most of us I looked at a lot of different MH companies before selecting Winnebago. One of them was Country Coach and I still read a CC newsgroup. I felt sorry of one of their owners who had been trying to order a basement door for a couple of months from the company and through a dealer and so far he has had no luck.
If I had chosen any number of other manufactures I too would have been SOL!
Just my two cents.
By the way I posted a couple of pictures of the damage and the repair process on my blog if your interested.
