Sorry not sure if this should go here or in the build section but anyways. I can't smoke full packers, i only have a small electric smoker so i've just been smoking flats. Well i want a bigger smoker anyways and am wanting to build one that will fit a packer so I'm wondering what a typical brisket's size is? My thinking for my grates was possibly 13" deep by 20" wide. Would this fit most packers?
