Hi Tony,
I think your photo of the truck with two engines mounted on the back driving a double diff axle is misleading. Look at the rear view of the Army truck and you will see the 3rd axle diff offset to left, so left hand engine drives that axle. My guess is the 2nd axle has diff offset to right. So drive is much simpler than we thought. I am also confused about the centre photo, but maybe it is just someone's idea to build a display engine set up.
