Yes, thats a thumb drive, you can see in one of those pics the artist/song on the display, its playing from the thumbdrive. Very convenient with the voice activated sync stuff..
Yes, its the 5.4 in it, 4x4 crew cab, short box with 3.55s and the 6 speed auto. FOr mileage, I've been getting 14-15 city, and 18-19 hwy. I'm happy with that, for sure. My commute turns in bad mileage numbers on anything I drive.
My last car was a V6 AWD fusion, got 19 avg.
before that, 4 cyl Focus, got 24 avg.
My TJ gets 15 mpg avg
So getting 15 in my truck is just fine with me. 75 mph hwy is around 18, 65 mph hwy was 19.5 mpg. I also have only 2200 miles, might loosen up a bit still. Its used 355 days a year to drive to work, or to haul the family, really didn't want to go with another 3/4 ton.
I *really* like this truck. Seats 5 adults very comfortable. Rear view camera in the mirror makes parking and hooking to the trailer is retardedly easy. The traction + stability work so well, I really never use 4wd in it (I live down twisty dirt roads that never get plowed...).
