I see the cabinet grills fully rotted a foot up from the ground at the dump. Doors, frame, panels. The magnets get rusted over and the doors no longer remain latched and its downhill from there. The inside panel on the doors is thin gauge galvanized iron. It rusts. Just stick your grill tongs between the handles to keep the doors closed. Keeping them clean and dry is a challenge for most folks.
The older Spirit, Genesis and Summits cabinet models had SS304 doors with iron hardware that is more of a nuisance issue. Rust streaks, handles breaking off kind of stuff.
On the grill in the picture the water is coming from above. The water is rolling off the floor panel and collecting at the edges rotting the square tube and the door. I would guess the grill was only used occasionally and not covered.
Overall it looks pretty good. Just needs a little body work.
