He tows our dump trailer, that's a few thousand pounds empty, loaded down with building materials with ease. And on the weekends he tows his enclosed trailer w/ the drag boat, ect in it...that's a 12k # package. He's towed that from OR to AZ and back with ease.

I'm not saying it's the best...just saying he's happy with it !

PPE is one of them I am considering. I think it will be that or EFI live. Truck is getting serviced today, fixing some little issues, and getting ready for its first trip down to GG Dallas next weekend. I checked mileage again yesterday and got 15mpg bone stock hand calculated. 18 or better should be reachable with upgrades. I know lots of guys picking up 3-5 mpg with tuning alone.
