As stated here, there will be nothing left but dust on a frame when We're done with ours. We bought new so we would be protected with warranties on the big items. Maintenance and upkeep are my responsibility and I try to be meticulous. New gave us peace of mind. If I buy used, from a private party, pay big bucks, and the transmission falls out of it as I leave the sellers yard,the depreciation cost I saved goes to a new trans... That is just one thought.
As an aside... This was a banner year for RV sales. I wonder too how it will effect prices when these (and I believe there will be a lot of them) RV's are parked in the yard then dumped on the market "For the best reasonable offer".....after only having been used a few times.
