Featherlite trailers must hold their value. I know it includes an air dam and weight distribution hitch. What would a brand new trailer cost?? It is only a year old though.

I got a quote for a trailer close to that for $4995. Some options were different.

Featherlites do hold their value and that looks like a nice one. Also it depends also what part of the country. Here in PNW we get shafted on delivery. What you can by in the midwest can cost us double. I see some real junk for outrageous prices all the time when it comes to trailers.
