Although I appreciate the advice that you are providing, but, and I am not calling anyone stupid, but make sure you empty the coals out in a safe manner before putting it in the garage. I have witnessed folks who have dumped ashes in plastic garbage cans that didn't bode so well. I would also suggest disconnecting LP tank from gas gril, before storing in an enclosed space.Just put the grill in the garage when you're done.

You would also prefer the burners be the 304 stainless. I have had the burners fail way before the outer structureStainless needs to be grade 304 and not the 430 that is used to build all but the most expensive grills. Older stainless grills are a better choice for the beach. They were more likely to be made from 304.
To check a grill for 304 stainless, bring along a magnet. The magnet will not draw to a 304 panel, but will stick to 430 stainless.
sweet!!Hey Bob, long time no see. I bought a BGE in 2008. It has never been further than a mile from the beach, and all I have had go wrong was an acorn nut that secures the handle got corroded. Otherwise, as good as day one.
