Default MPG towing

Finally some trip experience to report:

1640 mile round trip from PHX to Petaluma and return towing a 2010 TM3326 using a 2004 Chev Suburban 1500 with WDH. Mileage calculated from odometer readings and gallons to fill tank. TV has factory towing package with four speed transmission and towing shift point over-ride function.

TV alone (not towing) highway mileage at 75 - 80 MPH = 15 MPG (AZ legal speed limit is 75 MPG).

TV Towing:
GCVW=11,100#
original 15" factory tire diameter
3.73 axle ratio

Travel to Petaluma from PHX at 60 - 65 MPH = 10.5 to 11 MPG (used shift point over-ride for entire leg of the trip).

Travel from Petaluma to PHX at 60 - 65 MPH = 12.5 to 13 MPG (used normal shift point settings for entire leg).
