20,000 mile C&C with 2000 mile, MPG report.

[RVTRKN]

Just completed a round trip from Southern California (Rancho Cucamonga) to Oregon (La Grande) to pick up a 05 33.5V Arctic Fox I just purchased in La Grande, OR. There has been some questions on the MPG after break-in period (20K) on the 6.7 (07 C&C 6.7 at 305 HP) that it would be better. The MPG was hand calculated and the over head is also given, I was traveling at the speed limit so not to confuse a preferred MPH. The trip to La Grande is at 10K GVW and the trip back was at 20,000 GCVW. The only time I did not travel the speed limit was construction or safe speeds for conditions, and then on the I-80 from Winnemucca NV to Carson NV I ran at 70 MPH and when passing at 75. The terrain varies, so you will have to rely on your own knowledge of that part of the country, of coarse I will answer questions if asked. So here are the numbers:
