The upward visibility is lacking because of the shorter, shallower raked windshield that is more forward. If you sit high in the vehicle, which I like, it makes upward visibility difficult.
Most commanders have a power driver seat, it should be adjustable in height and in fact it will automatically move downward as you move it aft.
Tilting the vehicle nose up will help a bit, so leveling the vehicle may improve that. Just raising the vehicle, doesn't change angles, if you're only missing the bottom of the light by 2", then maybe it will come in view.
It's about the angles, NOT the height. Lowering the seat, give you a better angle to look up.
