Exterior Molle Window Panels

[GrannyGold]

I've seen these around for the GX platform but was curious if anyone had run into any problems with their windows while carrying loads. I know they're big with the 4R and FJ crowds. I've even seen them offered across multiple makes and models. I think the concern is since the GX (470) has a movable window that pops out, and the panel suction cups to it, what is the side lateral load like in motion. Any leaks from the window gasket possibly being compressed, broken windows etc. I've seen the newer Land Rovers even come with something similar from the factory but haven't been close enough to see how it's attached. Cheers.
