I have one - really love it - I'm averaging around 21 combined mileage - on the recent highway trip was around 28 mpg. The 2.7 is no slouch either it gets up and goes when needed.
The only detraction that I have is the stupid auto start/stop that you have to deactivate by pushing a button (everytime) at a stoplight, the engine shuts off to conserve fuel - it also shuts off the AC (which is Florida, in the summertime, is pretty stupid)
Other than that - It's been great/ I have the Lariat - SuperCrew cab - 2 wheel drive - but I did get the towing package so I could tow the boat.
