It’s a trailer sellers market. Last year I replaced my 20 year old, 4x6 open bed trailer, with a 5x8, that can do double duty, bring home old Cycles, as well as mulch.
Advertised the 4x6 for $450. Sold in the first hour the ad broke. I had about 10 replies before it went, and had multiple offers above my ask. This was a well used trailer, with some rust, and chipping paint.
