I sold a trailer in a few hours on horsetrailerworld a few years ago, but it was the sort of “deal” I knew would go fast, older trailer in great condition but not very expensive (it was a 20 year old Trail Et). So it “fit” the sort of buyer who can show up with cash.
The last trailer I sold, I took to Hitch and Tow in Aiken to sell on commission. I felt it was at a price point where maybe more buyers than not would want to finance it and that made the deal more complicated, for me… not for Hitch and Tow! So I got a little less than I hoped and exactly what I expected, and the difference between the two was a price well paid for not having to deal with tire kickers or people offering me a payment plan. Also, I have limited space to store a trailer and the new one was getting delivered in a week.
So I guess it mostly depends on how you want to deal with selling a trailer.
