@CO_MojitoI have an alienshade front shade and run mine under my JL Sunrider. its a snap to open with the shade up, while still in the vehicle. Basically, unclip the SR clamps, push up between the shade and the windshield header with your right hand, grab the SR with your left hand, out the window, and push back. no need to remove it. Closing is just the reverse. Reach out the drivers window, and pull closed, lock clamps. you do need to move the shade out of the way a bit when opening and closing the clamps but it snaps back into place.
I neglected to mention in my earlier post that closing the SR while you are sitting in the JL is also easy, easy.
