We hate troubles with our small Class C when out and about in it - and we have been blessed by very few troubles with it. Some folks assume that "troubles" will come in life and don't care to be negative-thinkers enough so as to figure out how to insure that ownership troubles are minimized when shopping for an RV. Added complexity means more chances for failure. I think there's a niche in science that studies that relationship.
Our Class C was pretty much fully loaded and optioned when we bought it. It had sat on the dealer's lot for about a year before we bought it (hence, the coach batteries were about ruined and the roof vents were close to being sun-cracked).
It took me a couple of years before I figured out why it had most likely sat unsold so long - it had no slide(s)!
We love it's options, features, and reliability and plan to keep it running and usable for many years. I'm hoping beyond hope that gas powered recreational vehicles are allowed to stay on the road long after run-around daily transportation has all been converted to electric powered personal vehicles and electric powered public transportation vehicles. :)
