I've had an 18.5 for several years and have wished for a good part of that time I had the larger 22.5". The main reason is for doing ribs. I'd like to do more ribs without them touching the sides. I know you either cut racks in half or you can skewer the ribs to fit more on the 18.5 but I'm not really interested in preparing them that way. Additionally, there are times when I'd like to do more than 4 butts. For those that have both, what are your thoughts in having both of them? I don't want to have buyer's remorse a 2nd time!!!! Additionally, I just got an amazon card at a work Christmas party that would pay for 1/2 of it so that is kind of prodding me along
