We just finished a 5000+ mile trip through the Rocky Mountain states and averaged 16.2 mpg for the entire trip. I use 5th only on flat roads and above 50 MPH.
Interesting data BM. Historicly we have averaged 13MPG/US towing our GVW 5,800lb dual axle
23' with a 3.5 V6. We would have spent $300. more for fuel doing your same 5,000mile trip. Note we do 60MPH on the highway so if we dropped to 55MPH we would save a number of dollars.
