The Dodge Ram HD heavy-duty pickups have the power and weight to tow heavy loads for long distances with big comfort for driver and passengers. The Mega Cab is designed to be the flagship of the heavy haulers. The Quad Cab may be big, but the Mega Cab is bigger. It comes down to choosing whether cab space or bed space is more important. For the best ride and handling, our choice is for a 2WD Ram 1500 Mega Cab. For best control handling heavy loads, a 2WD 3500 dually with the Cummins would do the job. For heavy hauling followed by accessing rough terrain when you get there, a 4WD 3500 single-rear-wheel model would be the ticket.
