Anyone know of a single source that provides GVWR, more specifically the Gross Combined Weight Rating (GCWR). Aware it is based on engine size, transmission, axel ratio, wheel base, and vehicle weight. And it is manufacture. Problem is they all do not post anywhere. Some may be on the door panel, others seem to be a secret. My GMC specs were buried in the operators manual. The listings for tow ratings are useless without this. My current tow rating is 15,100 lbs, but the GCWR is 22000, with the Truck GVWR of 9200 lbs. unloaded the truck weighs out at 8000 lbs, that leaves 14,000 lbs with the trailer loaded. It is no wonder many are overloaded
