I see a lot of people with some pretty high MPG. But I haven't seen anyone mention they're doing the math themselves and checked to see if their speedo is GPS dead nuts on. I know on my other rigs, what the vehicle claims for MPG and my actual MPG measurements are pretty different. I even went as far as using the same pump at the same gas station, and pumping slow at the end so it would/should kick off at full about the same spot. And both other vehicles I have done, the speedos were both dead on. I have yet to take delivery, but I'm wondering if any others have gone that route and still getting these mid to upper 40 MPG readings. Thanks.
