Our next unit will be a new Newmar. I don't lose sleep over depreciation, especially if I plan to keep it a while. I do understand the rational for buying used as you can find more coach for less money, and many of the issues with a new coach have been corrected. But having bought nothing but used in the past, there are plenty of issues with them as well. Theses beasts have and will always have mechanical problems, water intrusion issues, appliances that need to be tweaked or replaced, sealants that need to be redone. Buy what you feel comfortable with.
