Reply to:   RE: gas mileage question
Dave & Sherrie,
Just got back from our first major trip....averaged a little over 19 mpg for the entire trip fully loaded with gear and 3 passengers.  Highest was 24 mpg going 45 mph in Yellowstone.  Worst was 17 mpg going 70+ mph across South Dakota.  This is a far cry from the 16.5 mpg I was getting before I did all the work on tuning the engine prior to the trip.  I'll post rest of info on form below.
