A while back, there was a thread about a particular Suncast storage shed which was determined to be a good fit for a WSM and BBQing accessories. I just got one last month from Lowe's @ $178. It's the model GS2500, aimed at storing large trash cans and yard tools. The WSM does fit in it perfectly if you turn the handle so it fits in a recess in the lid. The footprint is about 3½' x 5'. Shipping weight is about 100 lbs, and it will fit, albeit tightly, in the back of a Jeep Grand Cherokee, if you take out the spare. There's enough additional room for a 18 or 22½" kettle, a couple bags of charcoal (but not in the humidity here), and your chimney, etc. My recollection was that, at the time of that earlier discussion, they were on seasonal close-out for $99. If it happens again, I'm getting a second one.
I realize that might not be of help in Ipswich, but thought I would mention it anyway.
