I have an 850SC and have put over 80,000 miles on it since 2008. In another 1 1/2 weeks I will return home after about 15,000 miles on this trip. On all my trips I have been on more than a few rough roads (nowhere as bad as the Great Whazoo's travels) and it has held up very well. In 2010 I returned to the factory as I was headed home and had the Arctic pac installed. Then about two weeks ago I again stopped in Cedar Falls, IA for some repairs necessitated by extremely high winds in California. A phone call to Rex and an email a day before the day I was to arrive and all was set for them to work on the camper. I could not have been treated any better anywhere! I love the cassette toilet but have never used the shower inside. If something were to happen to this camper I would never hesitate to get another NorthStar. Any questions about my experiences do not hesitate to PM me.
