So I will soon be moving up to Alaska which will require quite the drive up from Illinois (also stopping by a few friends' places on the way as well). I will be driving the truck with a good amount of stuff in the bed and everything, but I was wondering about if there was anything y'all would suggest to maximize my mileage during this longass drive? I can usually get around 20-21mpg on the HWY, but even a 1mpg improvement can make a helluva difference over this long of a distance (21mpg v. 20mpg would save around 11 gallons of gas which would be around $50 (depending on how much gas is through Canada b/c I have no idea) over the course of the drive)... I know keeping my foot out of it and not flying down the hwy at 80mph will save me the most, but I'll take whatever small improvements I can get I would love a tuner if they would just freaking release one for the 2012's, but would there be any improvement with a CAI, K&N replacement filter, Vararam, etc.? I have a tri-fold tonneau that possibly makes a negligible difference, but mostly it keeps the stuff in my bed DRY and secure, which is why I bought it. I'd welcome any ideas, and everything helps to pitch the need for performance improvements to the wife!
