change out the gears. what is your tire size, usual speed of travel. If your running 2K rpm on the highway the mileage will be worse than if you ran at 15-17 hundred rpm. On the level highway at 1700rpm and 62 mph i get about 17mpg. at 75 it drops the 13.4 mpg with 2000-2100 rpm

I d say the gears have a lot to do with the problem, if you have a mud tire that generally will take a couple miles to the gallon away. You could put a nice tall tire on it that would help.

Mud Terrain tires will definitely drop your mileage. I had some 35" BFG MTs on my current truck for a short while and my mileage dropped 2 full points. I don't think the 4:10s make that much difference. I had an 03 truck with 4:10s and it got better mileage than my current truck with 3:73s does. It wasn't much better but it was better nonetheless..
Also, driving with a lead foot or lots of stop and go will kill your mileage quickly...
