Truck bed rack?

Need some help. I’ve been searching for a truck rack that allows the rear of the RZR 570 wheels to sit in the bed, and the front wheels up on the cab. What I liked about this set up is that the tailgate is closed and the RZR is IN the bed rather than above/on the bed rails/rack. Does anyone have any info on this type of rack? I need something to allow our bumper pull camper.
