I was wondering if there is a websit for trailer like theres is for cars. (Kelly Blue Book) I am not really to sure on the price of trailers. If there is a website can you let me know thanks. The trailer I am looking at is a 2004 6x12 enclosed Carmate. side door, back ramp, new spare tire. The guy is asking 2500 is this a good deal or not. Thanks again.
