Clearance over bed rails enough for a toolbox

How much clearance over bed rails does a hitch with 14.5" to 16.5" of vertical adjustment give me? It is the Reese 27.5K that Ford supplies on the F450. 5er is a Keystone Montana. I have no way of checking since I am many hours away from dealer and neither truck nor RV are delivered yet.
The problem is I may not be able to buy it after I get the rig due to time constraints and remote location.

I have an under bed rail toolbox just to not block my view of the hitch while hooking up. My F350 is just for towing so no reason to worry about needing 4 inches of bed space for plywood or studs. I still have hauled 4x8 sheets of plywood.

If you get the high stop light camera you'll still be able to see the hitch. Also as others have mentioned I've in 7 years of fulltiming I've never needed to do a 90 degree that would interfere with a bedtop toolbox.
