Am I Calculating This Correctly?? Silverado 1500

I have a truck that weighs 7300 pounds, a one ton diesel. I haul a fifth wheel that weighs about 8500 pounds. I wish I had more truck, better acceleration, much better brakes too. Uphill and downhill are my shortcomings, but flat and level it seems fairly well balanced in all the conditions I have encountered. Combined, it is 42 feet long.

You have a light truck, a heavy trailer, and a family depending on your choices. I would really like to see you with a bigger truck.
