As for factory, that I don’t know. Perhaps it was a dealer installed thing. But, I do know a fellow that has his pickup box mounted on a dump system like yours. The box is mounted to the lift frame. The rear of the truck frame is shortened to accommodate the box when it pivots. The frame is shortened to the first crossmember from the back. The rear fenders are not bolted to the running boards either.it is pretty slick. The box does ride a tiny bit higher than normal and it is discernible.
