Whoa! You'd have to get VERY creative to put that kind of a system on a full length car hauler. Either you'd have way too much weight behind the axles, or in order to center the weight correctly, you'd end up dumping the load back onto the car hauler frame.If determaned to use the car trailer,
make a slide in box that dumps, that way you will still have a car trailer as well as a dump trailer,
and your lower frame on the hoist would not have to be as massive as it can piggy back off the deck of the car trailer,
you would need to keep it loaded light, unless you add a third axel to the trailer, you would then end up with about a 7000 pound capacity in the trailer if the trailer with slid in box weighs in the 3000 pound range

The only other solution is a 16' dump box with 6K worth of axles under it. Sounds like a recipe for overload and hard to dump.
