This is my second 26 I sold the first but always wanted to do this setup. Honestly you lose very little when you do this. Can still grill and use all the accessories that work with the 22 and 26. I have a slow n sear and vortex I plan to still use. Only down side probably is mobility since you have no wheels and that can be added also.That's pretty awesome. Personally, if I ever acquired a 26 I don't think I'd ever have the guts to cut it for something like this, but props for doing it. lol
I could definitely see an 18/22 be done.
