Way back in 2008, sold our 1st fifth wheel in early October to a gentleman who drove more than 100 miles to check it out. Gave him a deal to take it off our hands before putting it into storage ahead of the nasty Michigan winter weather soon to come. Price it right, cast a wide net, and the right person may just come by regardless of when you list it.
BTW, I have not yet been accused of being mentally unstable, at least not recently! Good luck with selling your rig.
