^ that reminds me I was going to wrap mine (squigglies) with a single layer of gaffing tape for some friction, I bet just that will stop the windscreens from moving unwanted. Also was going to break out the engraver and have some fun with the aluminum - including a reminder not to King-Kong-crank the valves closed, which generally happens when I set it up in camp and a bunch of people are using it
When ours isn't camping it's always ready to be deployed as an outside kitchen at home - for stinky or especially smoky searing and cooking
