Love the box, but that ROPS is unlike any I've seen. When up, it would be curved forward toward the driver. I've never seen any CK20s with anything but a straight ROPS which, when up, leans slightly to the rear. Both the non folding and folding ROPS have been that way on every one.
If anything, I would think the ROPS is on backwards as the curve should probably be facing rearward in case of a rollback in which it would be more supportive than the forward curve.
Oh well, see something new every day. John
