I am going to be lookin at a 2004 Interstate 16ft. enclosed trailer with dual axles and electric brakes. I am unsure if it is 7 or 8' wide but will know when I go look at it. I also will be able to get the GVW when I look at it. I am wondering what a good price for this trailer would be. The guy said he paid $5500 for it new, and i know he used it for lawn and landscape maintenance so I am sure it had quite a bit of miles on it, but I cant think that would matter much, i would assume trailers have a pretty long life without major repairs. New brakes, new tires, etc pretty low $ repairs. I also know it has a fair amount of trimmer and blower racks inside which will probably be worth a few hundred or more $ so I can factor that into the price. Anyone with an Interstate trailer? How do they compare to the other brands like Haulmark, Pace American, etc???
