Interesting. I was thinkin....
The Mor-Ryde Suspension (and others) has a cross bar that goes across from one frame rail to the opposite frame rail (just behind the axles). What if you put one of these cargo bars from say the base/foot of the right-rear scissor jack up to the corner where that cross bar intersects the frame on the left. And then add a second cargo bar from the foot of the left scissor jack up across to where the right scissor jack attaches to the frame.
Basically, its one cargo bar between the 2 scissor jacks at rear AND one cargo bar at an angle from a rear scissor jack up to the frame cross bar.
