I have a 22” Blackstone too. It’s pretty large, no trouble cooking for 6 people. I went back and forth between the 22 and the 17 inch. Finally decided on 22 so I have two burners with more control. It does burn through the 1 lb tanks right quick though. I need to plumb in a QD fitting to my coach’s LP system. It has a 60 lb tank, so no biggie there.
I have a port on mine which is a new thing for me as I've never had that option before. So, I've got a splitter and hoses so I can run the grill, lantern, fire pit & stove. Which is how I like to have things setup. I had one of the trees that clamped onto a 20lb bottle and fed all that stuff also.
I'll carry 2-3 20lb propane bottles with me as backup.
