DeJaVu, haven't I seen all this somewhere else.
The 1st couple of tanks is never a good indicator.

 

I'm up to 13.44 mpg maintaining 80mph on the highway.

I have to say, I think the truck just took some getting used to. The huge mirrors inspire some confidence driving and parking. And now I feel cramped when I'm in my dad's Ranger.

It's still vibrating 45-55mph, but I'm not at that speed very often and I'm becoming acustomed to it.

I still find the seats and seating position uncomfortable.

I never get tired of looking at it.

 

Agent, Sounds like you're gettin there dude. Took me forever to get that lumbar adjusted right for me and the armrest on the door still seems like it needs to come up about 3".

Ford is gonna come up with a solid fix for that vibration eventually. If you haven't got it on the books with them yet you need to do it 1st chance you get.

Hang in there.

 

TrukMupper,

14.17 last tank!!!! That's doing 80mph consistently, pretty much all highway, and making an effort to save gas.

Looks like everyone was right about fuel efficiency improving a little.

Good advice on documenting the vibration.
