Thanks Rich; I noticed your location while reading thru some of these threads today. My unit was shipped by Ace from Prescott Valley this week, which is why your location caught my eye.
And thanks for the warning about rust. Whatever I end up doing, it will be with a heavy screen material so I don't impact airflow. It looks like the cart only has a 2 year warranty so I'm not too concerned about voiding the cart warranty if I have to drill some screw holes to hold the screening. Before I plugged the small holes in my previous 20+ year old Weber the mice loved building nests in it. Not very healthy having mice living on your grates.
