So I finally had a good bit to haul with the truck. Up to now I had only hauled about 300.lbs in the bed. Today I hauled about 800 .lbs. I reset the trip computer to see what kind of effect this had on gas mileage and to my surprise the trip computer showed 25 mpg. On a 12 mile trip that included some stop and go, and a bit of 55mph driving I ended with an average of over 23mpg. I definitely don't get that mileage doing the same route with an empty load, so my guess is that somehow the load threw off the meter. Anyone have any idea how or why it would have that effect? On the way back via the same route but minus the load, I averaged a more typical 18-19mpg.
