This above topic was asked.... in case additional height was need in the cargo area
I found this answer;
We couldn’t advise driving with the rear hatch open but, sure it could be done.
And nothing inside the hatch will block the vision system, but if you have the hatch open you will not have your rear vision camera at the proper angle.

Of course we know we can leave the hatch open for camping tent!
The rear shock should be pneumatic, self-leveling and have a lowered load mode to make it easter to lift items into the high hatch.
