Hi, MSRP for my truck was $53500 incl freight/PDI, and I got it for $40200 + tax which included a Costco discount. I don't have any dealer recommendation as I wasn't overly impressed by any of them that I dealt with. I bought it from Sherwood only because they could get me the truck because they still had allocation for factory orders. I get 14L/100 in town, 11-11.5 around 110 kmh, and 12.5-13 @ 120. If I were to drive @ 90-100 it would be around 10. You're pushing a lot of air with the truck so fuel economy really takes a hit when the speeds are high, Ecoboost or not. Good luck with your search.
I really like the 3.7. Lots of power. when it hits 3000 rpm the engine jumps to life. It's a very quick truck. I thought I would be dissapointed with the power but I'm glad I went with the engine.
As for mpg, I live in an area with lots of traffic lights and hills so it's not very good. I average 15 mpg city. In a flat area I could see getting 17 or 18 mpg easy. On the freeway I've managed to get 26 mpg on a 1 hour drive. On that trip, with city combined, I got 22 mpg. Not bad at all for a 4x4 truck
