Not for sure what hitch they come with, but any class 3/4 hitch would be good to 1000lbs with a weight-distributing hitch.

A lot of class 4 hitches are good to 1000lbs Weight Carrying.

sorry, i can't be more help than that, but you should be able to tow it no matter what hitch is on there.

with that much tounge weight, i would think you would want a weight distributing hitch whether it is required or not. I would think it would ride and handle a lot better with the torsion bars hooked up.

just my thoughts.
