Re: Hand Calculated Mileage figures, post them here!
Towing #6800 in a 7x16 tandem axle trailer. Ceiling is 6.5'. Low: 10.5mpg @ 75-80mph w/ headwind. High: 13.2mpg @ 65-70mph no headwind. Lie-o-meter is consistantly .1-.2 mpg
higher than hand. No complaints yet. I will be adding airbags and a sway bar to the rear. These longer springs seam to squat easier while providing a better ride. Tow/Haul downshifting is very aggressive.
We are currenlty in Chamberlain, SD
. Off to Mt. Rushmore today and then heading over the big hills Thursday and Friday.
