I was getting 16-17 mostly city when I calculated without the trailer. I always pull the trailer so I figure my mileage with that. 10-11 with the trailer so I assume without has also remained the same.

As it is a new truck, I'm still unsure of what I'm getting. It appears to be better than what I got with the 4.9 though.
I started keeping track on the 1st of this month, so in a week or two, I should be able to calculate fuel consumption with some accuracy.
I'll post it as soon as I've got the figures.

'07 F150 XL, Rcab, 4x2, 4.2L, 3.73 limited slip, 265x75x17
Owned from 0 to 30K miles. During that time I consistently got 15mpg. 2 or three tanks I got 16mpg from driving mainly highway at slower speeds and only one time did I ever drop into the 14's. And that was from a week of heavy traffic, 25 miles each way.

It wasn't great, but at least it was consistent.
