Bluedog,
I think the better question is should he be called mentally unstable if he ever bought an RV. Motorhomes are the worst.....
In reality, if you have to get top dollar and you are not paying storage fees, you might wait until people have their tax return in hand and are thinking about spring.
If you need to get rid of it fast, this is the time to sell it because the bargain hunters are always looking.
