do you know if he did this from an open bed ?
if so, then Im sure he was happy as just going with a solid tonneu gave me an increase of about 1/4 per tank.
I ran 5 separate A-B-A tests with my ranger when I got my tonneu
1. w/o: drove from my home in Naples to Miami airport, and return. 3/4 tank of gas just to get me there.
2. with tonneu: less than a full tank of gas there and back.
3. w/o (A-B trip only): drove to Ft Lauderdale to pick up a scooter, about 37 miles shorter than driving to miami AP, used 1/2 a tank, just about exactly.
(cant use the B-A part of this trip due to adding the weight and height of the scooter in the bed)
4. with: to almost the same exact area as #3 (maybe 3 miles away) to look at a car, entire trip took me a little less than 3/4 tank
5. with: back to Miami AP, but had some suspension work, much taller tires (60mph read as 55 on odometer) and a full tuneup done prior to this trip, closer to 3/4 than empty for the entire trip.
all these drives had very similar conditions (as anyone in SFL knows, our weather is pretty consistent regardless of the date)
