Does anyone out there with a smoke vault (or any other vertical propane smoker without a separate door for the trays) find that it take a lot longer to smoke that "it should.?" I know there are many variables, but it seems to me that every time I smoke it takes a lot longer than it should, and I theorize that that is because I have to open the door every 45 minutes to an hour to add more wood, which the consensus here is each time I do that it adds 20 minutes to my time. So, let's say I have a 5 lb butt. It should take, up to 10 hours. But If I open the door every hour to add more wood, it would take me around 14 hours or so. Does anyone else find this to be true? I get frustrated and don't want to do it b/c I can't even get up at 6:00 am and get dinner ready for my family. I did a 2.5 lb cut of brisket to test my chops and I had to pull it early after 7 or 8 hours on the smoker. Am I paranoid, how do you make your smoke last more than 45 minutes to an hour?
