If you stay out there in the flat lands you will have the power you need with the 1500. But if you go west to the mountains not so much. But the 2500's will handle the trailer in the winds better. With the way we use our trailer, and the terrain here I would not think about a 1500 truck. The 2500 trucks are really are built better, bigger brakes, better suspension and tires and heaver drive line components. And for not much more than a 1500 after adding the options for the heavy duty towing and payload. That still leaves you short of the 2500 truck.
