Using 2000# as a "breakpoint", as Bill suggests, you could leave the tune alone. The 1500-1800# in the bed is going to be harder on your suspension than it is on the engine or transmission, so I'd try to keep the speed down with that much weight aboard. In fact, I think that much weight is a bit over the GVW or axle rating for your truck. When towing, you only add the tongue weight (usually 300-500#) to the GVW and axle loads.
