This sounds like a good mod for the flimsy crap OS sells as extended legs. They fail to inform you before you buy that it's not recommended to clean/brush the grate while on cooker.
And Jack, my cooker was up against a stockade fence in a protected area of the yard too. We had converging storms that day unfortunately. If I can get my OS sealed or maybe by taking the legs off it will take a bend better, anyway if I can improve it I will try to put some conduit extensions on the bugger.
