i have gotten just over 22 mpg several times on long road trips with my LB7. was able to get just over 600 miles to a tank

605 miles / 27.2 gallons = 22.24 mpg. cruise control set at 68 mph

didn't burn a drop of oil ether :woott:

I've never ran a stock tire nor has my trucks ever weighed less than 7800 empty. I got 18 mpg weighing 8400ish on 33x12.50's that measured out to 32 and some change in the Carolinas, and the truck had 11k miles. I may have gotten 20+ with the 265's and a lot less weight but I doubt it.
