Wheelbase for my 3500 Regular cab 4x4 is 134. 7 inches, for a 3500 Quad cab 4x4 it is 154. 7. That additional 20 inches is between the engine and the fuel tank. I think with all of the other things working agains't these pumps that 20 inches can make a difference in long term performance. Like I said I think it can make a difference.
I think that 20 inches also shows up in how rigid the truck rides which also makes sense. I had a 2000 3500 Quad cab 4x4 and it seemed like the frame flexed more on it then on my 2002 3500 Regular cab.
DC should of done 2 things to the longer wheel base trucks. Put a stronger LP and a heavier frame. JMHO
