Yup . I have a cart with 2 levels that's on wheels . I just move it with my grills . I have water proof storage out there and quality covers for the grills .Thanks, yes the concrete patio runs almost 3/4 of the back of the house, but is uncovered. I think I will leave grills/smokers to be mobile and do what you do, move them out when weather is good, undercover when raining or snowing.
Sounds like you'll have a nice set up .
