Man, reading through this makes me feel much better about "overpaying" for the M101A2 I picked up last weekend. I admire the work effort and the originality!
This one has an electric brake 3500lb axle (dexter I think) with 6x5.5 wheels that match my other trailers and chevys. I haven't tried to see if I can make it dump with locking down the electric brakes.
