It's pretty nuts, for sure.
We bought a new (used) Toyhauler last month, following selling our TC last fall for what we paid for it (used) in 2014.
After combing a 1000+ mile radius for a couple months and seeing anything decently priced (for this market) disappear very quickly, we found one that we thought was decent priced (for the market).
Had to scramble to snatch it up and I recall the price being barely under NADA low retail, a month ago.
Now, low retail is about $6k more than what we paid and $14k under "average" retail. With average retail being about $8k under original MSRP, or about the same amount OVER what would have been a good sale price, brand new, in 2017.
If it wasn't our older son's last summer at home, I swear, I'd sell the truck, camper and boat and buy a big mattress topper to smooth out the pile of money we'd have stuffed under our mattress!
