I have 13700 on my 2003 now and the total average for all driving is 17.2 mpg, according to the computer. I usually get 20 +/-1 mpg driving 65 - 75 depending on the wind and get 17 +/- 1 mpg driving to work and around town. Pulling a 18' car hauler with a 4 door Tahoe on it I got 15, but there was no wind and I drove 60 mph. Not because it wouldn't go faster it was raining like a monsoon was in progress. The D/A barely knows the trailer is back there.
