tow anything approaching the max tow capacity? How does the engine power handle the load? What happens to the fuel mileage? What are your overall impressions of the truck? I will be in the market in the next 6 months and I am torn between the 2500 with Cummins diesel and the 1500 with the eco-diesel. The mileage difference is substantial, and I will only be towing 10-15% of the time.
