From my calculations I got between 10-11 MPG on the trip up to R&V pulling the Jeep on the trailer.
$60 in diesel at $4/gallon = 15 gallons
Did a little better on the way home as expected.
I can get this if not better than my 03 Sierra 1500 plus the difference in cost of the fuel.
If the DP tuner can get me around 16 it would pay for itself in a year I imagine.
I thought it would do a little better being lower and not a 4x4.
Here is the truck, I imagine the bed to weigh a bit. I had the truck weighed and with a bed from a Canyon in the bed it was 7740 lbs
