I also have the 3.92's.
What is getting me, is mine has averaged 12.9 (hand calc'd) for the life of the truck, and I DO NOT hot rod it. Drive like grandpa by most peoples standards. It has 2300 miles on it right now.
2 tanks towing, and the rest is normal driving, no hot rodding or anything like that. I'd say ~ 25% or less of the 2300 that are on it were towing.
Most of my towing is a 3300 lb boat, but 2x a year I drag my heavy camper 100 miles to my hunting property, and then back at the end of the season.
Most of my driving trips are < 10 miles 1 way, so that may be some of it, but man, this thing isn't getting even close to the mpg everyone else claims, and even the dealer is surprised I ain't getting better as well. They said most people get better mpg than the window sticker says.
