Hello Crusin - we do have another website dedicated to utility, cargo, flatbed, landscape, etc., trailers that you can check out at
www.TrailersUSA.com. If you are looking for a horse trailer, check out
www.HorseTrailersUSA.com.
The trailers listed on those websites are by dealers across the US. I'll ask my team if adding the ability for individuals to list their trailers for sale is on the to-do list for those websites, and let you know.
Have a great weekend. : )
