First of all, welcome! I have the 18.5” WSM and have been very happy with it. We are a family of three and sometimes six depending upon which son is where. As has been mentioned, the only drawback might be the grill surface is too small for some things. So far the 18.5” has more than satisfied our needs. I usually like to make side dishes on another grill while doing a smoke. It sounds like you have that problem already solved with your gasser. One question I have is why were you selecting the 26.75” kettle? Are you routinely cooking for larger groups? If so, then the 22” WSM may be the way to go. Just a word of caution however. Once you start smoking, I’ll bet you a beer this time next year you’ll have a kettle too. Good luck and let us know how you make out.
