2015 Chevy Silverado 2500HD, Improving Unloaded Ride

x2 on dropping tire pressure. On my F250 diesel unloaded I run 42 in the rear, 48 in the front. Tires seem to wear evenly. I air up when towing the trailer or hauling heavy load. I do not air up towing the boat as it is a very short trip to the ramp and the lower pressure gives better traction pulling out of the water on the steep ramp. Pumped up to 75 psi with the Jayco on the back, and I know it quickly if I forget to air down, beats me to death over every hole.
