What year is your Infinity QX60?

Does it have a factory tow package?

Check your owner's manual for your GCWR (Gross Combined Weight Rating).

Does your owners manual "Forbid" the use of a WDH (Weight Distribution Hitch) or does it "Not Recommend" the use of a WDH?

That vehicle has a very short wheel base and a WDH would be best if you can use one.. I'd recommend the "Anderson WDH" if you can use one at all. Do a search in this forum for "Anderson WDH".

Basically, you are asking for legal advise from a bunch of people that you know nothing about. Some of us may be able to make suggestions but NOTHING should be construed as "Advise"........
