I talked to Blake on Friday. These have the 11 liter detroit with the super 10s. Mileage is in the 500 to 600. I think Blake is right, these would be neat tow vehicles. The small Detroit is reliable, gets good fuel mileage, and has all the power we will ever need.
Just an fyi, when I bought mine from Blake, had about 13 to chose from, he had done a sort down to about 6 for me. We drove everone of them, and I chose the one I bought. It wasnt' the lowest mileage truck, it just rode and "felt" better. A 500k mileage truck would not be a problem for me to buy anymore, knowing what I know now.
Just my thoughts.
J & V where are you?
