fuel mileage?
I took my truck, 1996 2500 Cummins,6 spd, 11.5 - 3.73 rear, camper top, no trailer to Colorado and back. The fuel mileage was dissapointing 16-16.5 at 70, 15-16 at 80. Is that normal for this truck? The gearing seems to be 1 gear low for my use. I only use 2-4-6 shift. Is there any way to solve this problem short of an OD?

i just drove from San Diego to Omaha , then from omaha to Houston , then back to San Diego for the holidays. If i stayed at 65-70 I was getting 20 ish MPG. the big breaking point of these mototrs is once you go past 2k RPMs your mileage drops ALOT.
