Joe: What is stored on my Weber Performer Deluxe(WPD) when not in use: SNS Plus, SNS Easy Spin Grate, Weber GBS Grate, SNS raised Grate, SNS DripNGriddle Pan, Some GrillGrates, etc.,etc. I live in a two(2) Bedrooom Apartment in which I do not own a car, so, I store my WPD, WSM 18" ":Classic", and Weber Smoky Joe in the Car Port Patio Area.
Also, wanting to utilize more often my Rotisserie Investment by adding another Weber Kettle I would have it all set-up in advance which would ease the strain on days that I am feeling my 78 years old but wanting some BBQ via the "spin method". Also, not it being a total "set-it and forget-it" type of grilling; on a Large Weber chimney full of charcoal briquettes I was able to maintain a constant temperature of 350F and three(3) beers later my chicken wings were cooked.
Also, I guess I could store my BBQ Things like the photo below on the right but then starts my "wifey" problem.
However, you make a very good point!
