I replaced my stock shocks last week on my 12 Ram 2500. I had around 12,000 miles on them. I replaced them with Bilstein 5100's. I also have a MorRyde pin box on the 5'er. Long story short, towed with just the MorRyde pin box 1st. It helped somewhat. Just towed 200 miles with the MorRyde and new Bilsteins and the shocks made a big improvement. Roads were freeway all the way with a mixture of asphalt and concrete. Some of the concrete was pretty bad too. Bit the ride was fairly well controlled.
I never changed the PSI in the tires from the last trip. They are at 75r, 70f. I drove around some before this trip and the truck empty feels as good as when I air down the tires to 45r, 65 front. Overall a great improvement IMO.
