Ive smoked about 3 of these recently when I got my Smoke Vault. They come out great, but the damn things take easily 16-19 hours to smoke. That's with a 6-7lb butt. What gives? Im smoking at 225. Im using a Maverick thermometer and never opening the door unless I HAVE two, which might be once or twice over the cook time. The thermometer says 255, but my analog gauge says 225. Either way, im somewhere in there and I can't figure out if it is normal for it to take that long. It would be nice if I could get it done in one day or at least plan it better. This time I started it at 1pm so I could just let it go overnight.
