Due to financial commitments and the inability to ultimately sell our old home and carrying mortgages on 2 houses knocked us out of RVing for about 3 years. One of my family members suggested I sell the camper. I just couldn't do it. We ventured out a few times in that time period, but selling it ... nah.
Well, fast forward year one after finally selling the house, and finances began to turn around. Fast forward a bit longer and 6 weeks ago we traded for a new camper and for the last 5 week-ends we've been "on the road again!"
So it's possible, when a camper sits there may be reasons why.
I do know that for some people (like me), selling it is like loosing your best friend, even if it's never used.
