I recently got a '21 Rebel, super crew, 4x4, etorque 5.7 with a 3.92 rear. After it had 1,000 miles on it, I took it on a long road trip (1700 miles each way), that took four days round trip. I expected to get 16 MPG as an overall mileage figure for the trip, which was just a guess.
Day 1 was a 17 hour drive. The first half was on state highways with speeds of 55 to 65 MPH, and the computer told me I was getting around 16 MPG during that portion. Then I hit the Interstate, where speeds were 75 to 85 and I saw lots and lots of 9 to 11 MPG figures on the dash. The trip had me driving from sea level to 6,100 feet on Day 1, so there was definitely some uphill pulling along the way, though nothing you'd call steep, just kind of a steady rolling uphill drive for hundreds of miles. When I ended Day 1 my overall MPG figure was 13.7, which was pretty dismal.
Once I hit the destination end of the trip I did more driving around on local roads and my MPG recovered from the 13.7 figure, but I expected it would get destroyed again on the way home.
On the way home I reversed the elevation gain, coming down from 7,000 feet to just above sea level. The truck got better mileage the whole way, and by the time I got home, my overall MPG figure from the computer was 17 MPG. Despite hitting a low spot of 13.7 MPG, it actually recovered to a better overall figure than I had planned on at the start. Funny how it works.
It did get me thinking that it would be nice if manufacturers provided a "steady speed MPG" figure for 65, 75, and 85 MPH so you'd have an idea of what the vehicle will do on an interstate. The current "City" and "Highway" test tell you nothing about running it at interstate speeds.
The truck ran like a champ. It's a very comfortable long haul vehicle. Very happy with it so far.
