Smoking Fanatic
I think (1) 2inch valve is enough. Thats all I have on my pitmaker vault and it will hold 15 briskets. You can add another pipe and put a cap on it if needed for higher temps. Always want to put thermo at grate level. You can drill a hole in side at each grate level and add small bolt when not used to keep heat and smoke in. Also Big Poppas Smokers makes a UDS kit you can buy with everything needed. I have a spare 10cfm guru setup as well I dont need anymore if you are interested
