I use NV-4500 Transmissions ( 5 speed OD). My differentials are 4.89's. I use 36 inch STA Super Lugs on all my trucks. I can run any legal road speed. Typically, I run 60 mph at 1950 R's. Last summer, with the carryall, on a long trip of 3411 miles, My overall fuel avergae was 25.9115 MPG. This included 539 miles of Primitave gravel road, running for hours in 2 & 3 gears due to quality of road. I burn Cetane boosted Diesel, Power Service Diesel Kleen mixed at double dose, per Power Service Engineer's suggestion. I expect the M37 to get even better fuel economy since its lighter an has exactly the same engine/drive train
