On the 2 lane highway going 50-55mph I get 19mpg, on the 4 lane at 63mph and get around 18. On the interstate running 78mph I get 16.5+mpg. I have 285/70/17 tires so that works out to around 32.5-33in and 373 gears. I just pulled an empty trailer at around 60mph for 40miles and then drove though town for a few miles. Empty it weights around 3500lbs I got 13mpg.

update:
780 mile trip from WA to UT,
quite a few long steep grades along the way, my EVIC is very very close, reading 18.8, I did the math and came up with 19.2. the money I saved on this trip pays for the egr delete. And I've fallen inlove all over again

I was driving normally, half the trip was driven at 65-70mpg and the other half at 75-80.

2011 HO 3.73's, 4wd w/35's with 15,000 on it. I have never hand calculated but occording to the lie-o-meter I have never averaged over 14.5 or so on a trip over 100 miles....even if I'm easy on it. Usually average around 12.5 to 13 mixed driving. I have towed my boat (19 ft Carolina skiff ultra) to the coast about 4 times with it and usually average about 8.5 to 9.5 mpg over the 300 mile round trip. I do drive the speed limit or a little above on the hwy most of the time though...
