As mentioned, watch out for the canopy frame where it extends down along the sub panel. Also, watch out for the stiffener assembly as they angle down toward the front. As a matter of fact, when I started planning my panel I made a cardboard mock-up of the stiffeners to see what space they would consume. I have a Dynon D100 & D120 & I wanted them up as high as I could get them without having an interference issue. Study it carefully.
