To GV80 owners, what's your actual payload capacity and actual front and rear axel capacity? for 2.5 or 3.5....Should be in the plate on the door. Just researching what's the realistic towing capacity of GV80. A maximum tongue weight of 900#s from a 6000#s trailer might be almost all of the payload itself. The hitch hardware itself will reduce the payload permanently if it's fitted after production. Thanks in advance for your insight.
