I am considering a WSM and would like the 22.5 but it's almost $100.00 more than the 18.5. Would I be disappointed in the 18.5? I now have a Masterbuilt XL that works OK but would like a good charcoal smoker that I could take with me when needed. The best price I have found on the 18.5 is $257.00 and $340.00 on the 22.5, both with free shipping. I feel the 18.5 would be more portable if needed but will it hold enough meat. Any thoughts? Thanks.
