I always thought it would be nice to offer the option of a remote controlled dump box so you could drive up to the fenceline, or rock pile and dump the rocks from inside the cab. If the rock box were built with a sloped front, similar to the rear of a quarry truck, then no dump gate would be needed. The dump mechanism could be something similar to those on a SxS box dump, but controlled via fob. Also, make that front edge sloped plate either thick, or easily replacable in case it gets bent up.

Remote operation would mean no more pinched hands/fingers or having to keep your feet out of the way of the falling and rolling rocks. Our rocks don't seem to stay in place when you throw them on a rock pile. Seems they come back to try & get you.

Those were my thoughts. Anyway, it would an option so as not to make it more expensive for those that don't think it's necessary.
