If you want a 7000lb, wood deck 18' trailer with 82" between the fenders they are very hard to come by for under 2K in the new england area. I don't know what it is about the northeast but trailer prices are high here. I do assume you are talking about a new trailer. I'm sure you could find a used one for around that price.
I recently saw another post where a dealer in NC sells a 20' 14k rated trailer for just under 3K. Same thing up here sells for close to 5k or more. I bought a 7k, 20' tilt bed, wood deck, w/ 82" between removable fenders but had to drive to PA to get it for a decent price. Several dealers in NY had what I wanted but they wanted close to 5k. I bought mine for under 3500. Same dealer has a model like you want. It's an 8.5 x 18' wood deck HD flatbed for $2470. I don't know if you want to drive that far but check out H&H trailer sales web site. They have all sorts of models but the closest dealer is in PA. I like mine a lot.
