are just perfect for carriers. They have wood beam deck and are lowboys and are short . Low enough that a carrier could drive on without ramps, use the ramps though. I have seen them in tandem and triple axle styles and ball hitch and fifth wheel versions. Heavier Bobcats are 12,000-15,000LBS. Steel tracks on steel decks are just a accident waiting to happen.
