Think about the math here. With a 33" wheelbase (37" long chassis, with 4" wheels), that means you have 16.5" between wheels. With a .1875" drop on the center, you can rock 1/100 of a degree. Obviously that's exaggerated when you have a long arm sticking out, but come on. .010 degrees of rock is nothing. It's hardly noticeable. It doesn't affect precise positioning whatsoever.

Agreed.
Even with a 10' arm on there, if your manipulator needs to be accurate in placement to 2" or less, you really have a poorly designed manipulator that would be difficult to score with anyway.
