I have had a 18.5" WSM for 3 years now, and once a year cook for a big party. Last year I did 4 x 4kg pork butts from Turner and George, but for next year would like to add extra capacity and cook a brisket too. I have been looking at stackers to extend the capacity, and would be interested to know if anyone here has tried any of these, or whether there are other options I have missed. I have found:
ProQ WSM stacker - I doesn't look like they make this any more, I guess as they compete with the WSM
Barbecue Stacker (http://www.barbecuestacker.com) - UK made, so easy shipping. Looks like I need the deluxe one for a tight fit, but they only makes it for the larger WSM. The standard one has a join that makes it fit a variety of BBQs, but I am guessing that's not going to be great for low'n'slow.
Cajun Bandit (https://www.cajunbandit.com/18-5-WSM-St ... 8stack.htm) - looks like exactly what I'm after, but I can't find a UK distributor (and it's more money)
Any advice gratefully received!
