I'm shopping around and settled on a 5x8 high-side tube top trailer from Sure Trac. 900 lbs empty, no brakes mounted. The weight comes from the frame... lots of tube.
My plan is to to some axle work, add electric brakes, a tongue box w/electrical (battery, distribution), and use it as a combo utility trailer/RTT trailer. I have a telescoping rack design in mind. I don't know if I'll get to it this summer with what I've got in the queue already, but maybe I'll get lucky and knock the other stuff out early.
