A trip from Twin Cities to Wisconsin Dells and back going 60 to 68. No cruise, no topper or bed cover. I filled it up at the same pump at the beginning of the trip and the end and got 30.93 mpg. At 143hp its not a dog. They are still making these trucks.

 

With my 2008 Ford Ranger
4 cyl, 2.3L, 5-speed manual: 21 city | 26 highway

 

My 2009, 4.0 , 5 speed manual, 4x4 supercab, 3.73 standard rear end gets 21 in town and 23 on the highway.
