Finally took my truck on the "drive to the other side of the state" snowmobile trip pulling the enclosed trailer. Based on my old truck, I was only expecting 8-9 mpg, $400 in fueling up and about a 7 hour ride 1 way.
This truck did consistently 11mpg through the Wisconsin hill highways at 67-70mph, used only $200 in gas and did it in just over 6 hours 1 way. Did notice that the truck would shift down if heavy on the gas up the hills, but with a little feathering of the pedal, it didn't happen as much.
Totally blown away at how well this truck performed this last week of driving through the state. Makes me more glad to have made this purchase.
