I had a good friend with a 4x4 Dodge dually diesel I loved to look at, but for years I avoided them because of how they rode! That darned thing was simply unacceptable for a passenger. Only later did I find out that the 4x4 was the reason for the terrible ride in his(empty of course, and the tire pressure may have been tops too). My 4x2 with MorRyde rides like a Cadillac (well, almost), anyhow I love how it rides.
