FYI....KZ is a much better built unit then any Thor product. KZ was still a family owned business run by its founder. It was one of only 3 offering a 2 year warranty. I had a major problem with my Durango and the factory repaired the delam and replaced the entire roof after the warranty was over and didn't charge me a cent. Read the posts of Thor declining claims on 1 month old units. If you ever toured facilities in Elkhart you would agree that KZ was a much better unit and a better run company caring about its dealers and end users.
