PLEASE check the owners manual about the weights. On earlier models it said weight distributing hitches were not advised.
This from the RAVE owners manual for a D2:
An equalizing or other form of weight
distributing hitch should NOT be used with your
vehicle
Also, the book for a D2 says 550 pounds max tongue weight.
Please consult owners manual, it could save you from an accident, rollover, or hostile attorney. If you want to ignore the book, check with your insurance agent to see if you will be covered, in some states you might not. You also could be cited in some states.
