I'm glad to see that you guys are getting around 23mpg on longer trips. We have taken 2 other trips that were about 300 miles each -- all freeway. We have always gotten about 17-17.5 mpg. I figured that maybe the 4.4 just drank more fuel so I didn't worry about it.

I was suprised on this trip which included lots of passing in the mountains to get the 23mpg. Who knows.
