13 mpg semi

Personally, I think the mpg results by a semi mfr are flawed as all the tests seem to be done on flat roads. Test them along I-81 thru VI, PA & NY. Hills out west. Headwinds and crosswinds. Then see what they claim.

I agree, they are always going to optimize the test results. But, it's still better to get 13 MPG on a level road rather than 7 or 8.

I'm still waiting for a 30 MPG Suburban or Expedition. :)
