Ok, so I didn't have any takers on my model questions below. So, here's another question. Did Case make any running gears with a floating or rocking front bolster? All of the pictures I've seen of the VWTAs, etc. have a solid front bolster (ie, single piece with the front axle). So, the gear would be rigid or require the box to flex in order for all 4 wheels to stay on the ground (in the event that the reach was allowed to rotate). This seems pretty inferior (albeit cheaper) compared to many other brands of gears with rocking front bolsters. So, what the heck? Somebody bale Case out on this one.
