The QX56 is the same with respect to towing as the Armada, except the payload is likely lower due to having more equipment. Combined sales of the two is around 25k per year, which is quite low in the full sized SUV market. Please verify your actual payload as equipped per your tire and loading sticker, as no one has the base curb weighted truck, not even the luxury branded ones. Also, please verify your receiver limit. I am not aware of any SUV after 2006 model year that has more than 1000 pound receiver limit when using a WDH.
