My wife and I are going to my camp this weekend. It's a long trip on I 95 mostly in Maine. I'll have a canoe on the roof of the F350 diesel. The canoe is aerodynamic, but it will add a lot of frontal area.

The closes mileage guess gets a 10 buck prize.

Guestimate
 

11.8 L/100Km

I'm going with 19.22 mpg

I'll take 19.23 for $100 Alex.

19.3
What kinda bucks are we talking about here? Like winning a TOy-Yoda?

1mpg... is this like The Price is Right?

19.5!
Judging by your gaslog, 19.2 to 19.6 would be a safe betting margin.
Prove me wrong and get over 20! Canoe FTW!
