I went with the BIG TEX 70CH 16'. It has dual axle brakes, wood floor, breakaway switch, 7000gvw and ramps. It is wide enough to handle my K20 with 33-12.50x16.5 tires. The size of the hitch ball is dependent on the weight of the trailer, Most in the 6000lb and up will be 2 5/8" for safety. I pefer wood as I block and nail the load down so it won't move.
Changes I would make after 3 years would be 18' maybe beavertail (rough country they would hange on everything) spare tire when new, longer ramps, "D" rings front and back(welded my on on after a year) and a winch or comealong.
If you went with a flat deck over the tires you start to get pretty high and definitly need a winch for dragging things on. If you haul just cars then one designed just for them would be best. Mine is a alround utility trailer.
