After thinking about this beast and weights wanting to haul, I may be putting motor under cab like 1:1 machines using the reduction gearbox same as the 1:1 machines. Gives me more room in front of axle. Yes over engineering this heavyweight. I've been crunching the numbers and just thought of the differential aspect, I did not figure that into the final rpm. I'll go and count teeth on differential pinion and spur gear and find out numbers. Thanks guys.

Yes that's 4:1 ratio.
Cheers!
