i got one, went back and forth between that and some of the pit bosses, ended up deciding on the Camp Chef. and its pretty amazing. there is no water pan, but you can easily put a pan on the grease catch and not lose any cooking space, and there is a ton of cooking space! also the added smoke box makes a HUGE difference, i made a chuck tender roast and it had a super thick like 1/4 inch+ smoke ring!
the not being double walled, well isnt much of a concern for me as i live in FL, they do make a jacket for it if you live in and want to smoke in a cold environment.
the drawbacks, putting it together was pretty time consuming, im not much of a handy person, but im not stupid either, but there were a few times where it was just awkward and hard by my self to get screws in.
the handle get HOT when smoking at above like 300, i normally smoke between 225-250, but the few times i went to 350, it was like dangerously hot. i usually do the white cotton gloves with nitrile gloves over it when smoking and is usually enough for opening the door and moving food around and sliding racks in and out a bit, but not at that temp, i still cant touch the door handle. that would be a mod id suggest if youre handy like that, is a thicker silicon cover for the door handle.
i think youd be fine with either a PB or CC, i do like the ash cleanout on the CC way more than the PB, personally. any questions, feel free to ask!
