Hi wilber; no, I'm not saying it, I'm quoting it from Curt's web site but I do agree with them because it makes sense to me. If the truck is within specs and carrying part of the trailer weight, then it is towing the remaining weight. And I think the word 'towing' and max towing weight is being misinterpreted. I interpret it as the truck being able to carry a certain amount of weight, AND tow a certain weight. As a radical example, if I dropped a 3000 pound weight in the bed of my truck, I could drive around all day with that weight and still have the capability of towing/hauling 15700 pounds. And you are correct on the gcwr. I'm not sure what my status will be until I get the trailer and get it weighed.
