A 36 gallon tank is crazy too, how many miles can you get out of that with the V8 if you aren't towing, just like normal daily driver duty up there?

I haven't tried a MPG run of "unloaded, highway" but if the MPG average is around 14, it estimates 515 miles when it's full. I think a few people on the forums have managed to get 650+ out of a tank with straight (calm) highway driving, likely with the 3.5 EcoBoost. Unloaded, the 3.5EB does better on the highway than the 5.0, but towing, they're near identical.
