You may be right about the spring issues - but Ridgerunner says he has a harsh ride when unloaded which isn't consistent with the idea that his truck might be equipped with "comfort" springs. I would think that he would have a good ride while empty with "comfort" springs or good hauling performance with the other version of the springs. In this case he has neither. I'm not saying you guys are wrong - you'd know better than I would since I've not had an issue with mine - but I still think hauling a 600 pound load centered over the rear axle (or worse - behind the axle in the cargo area) over 4-6 inch potholes without bottoming out is too much to ask of any midsize SUV.
