There is a Coachmen Owners Association. http://www.coachmencaravanclub.com/
Always good to check with other owners once you've got one sitting in your own driveway.
I will say, one of my son's travels for his job like his Dad & I do. He has a Coachmen Kodiak TT that he bought new about 6 years ago. He's like us and doesn't get to choose his assignments. So he's spent winters in deep snow in St Louis or N. VA and summers in FL and AL. The only repairs he's made is check and sometimes redo the caulking every year.
His family joins him during summers or holidays when he's out-of-town and they are all 5 comfortable in his 30'er.
The reason he picked the TT was as an Ultra-light he was able to pull it with his Toyota PU.
