I am just curious as to how much more it can pull. We drill water wells around here and we haul some heavier equipment and I seem to have a habit of hauling old trucks home as well. And my half ton now can do it but last summer it would overheat at times and just didnt have the power to pull some of the things we have. I spoke with the original owner of this 03 gmc and he said highway it owuld do about 13 and in town about 11. But i am on the highway a lot just to get to town. But the dealer thinks something is wrong with my transmission on my current truck, which nothing is wrong with it and his reasoning didnt make sense. I am only 21 and when I come in there i cant get a saleman to take me serious. COuld be their loss on it
