I can see how manipulators get extra space though, but I like electronics space more than manipulator mounting space.
While the inboard wheels do take up a little space, the space gained by moving the wheels inboard is much greater. Moving the wheels inboard allows me to move the side rails of my frame outward by 2.25 inches.

Quick math shows that I gained 135 square inches by moving my rails outward by 2.25 inches on a 30 inch long frame, and lost 45 square inches by making 4.5 by 2.5 holes inside my belly pan. This gives me a net gain of 90 square inches for electronics on top of the additional space above that for mechanisms.

Ok, I would mount the gearbox using the 4 bolt holes in line with the output shaft. If you support the other end of the shaft, the fact that the holes are practically in a line won't matter.
