yes they do, i find i get like three days worth from one tank, and tanks are about 20 apiece here, i want to convert mine to natural gas but dont know how my electric was nice and easy but its nice to have a flame
While I have enjoyed my propane smoker(holds a steady temp, and the price was right), I just bought a WSM, I missed smoking with lump and wood(although with my GOSM, I use a large cast iron pan instead of the chipbox, that I load up with lump, and wood chunks).
My use is about the same as some others, 28-30 hours on a tank that cost me about $18 to refill. Charcoal use can add up real quick, not to mention the storage space. As far as flavoe is concerned, I burn RO lump and chunks in my GOSM.
