Some of us have bought this cabinet from Sam's Club:
CabinetIt has locks on the door and drawers. I took the wheels off the Elite and bolted the smoker to the cabinet (5/8" x 1.5"--I believe-- bolts through the wood top into the wheel holes). Once you've got the smoker secure, you can then chain the cabinet to your deck by running the chain through the corner/back of the cabinet on the door side of the cabinet. You'll have to drill through the metal cabinet but you won't be fooling around with the smoker's warrantee that way. You could just run the chain around the front handle, but it can be unscrewed (8 screws).
You could also purchase the stainless steel stand that some have and drill/bolt the smoker to that, then chain the stainless steel stand to the deck. The smoker could be unscrewed from the stand, however.
I'm from Chicago, and the only concern with my cabinet would be how the wood top can be water proofed from the weather. Here are other Cookshack setups that might give you some ideas:
