I tested the new springs over the last two days, and hauled three yards of drainage rock (one at a time). I took a measurement at the rear wheel well loaded (32 3/8") and unloaded (35 3/4"), and I took a pic of the truck with 1500lbs of drainage rock in it. It sits quite level with that load, so as long as it is similar with my trailer attached, I'm happy.
