An original BBQ smoker design made from a recycled hot water heater. There are a few benefits of using the water heater as a starting point...
This one was lined with porcelean, the same kind of coating used on cooking pots. A hot water heater may have a gas and temperature control system that you could use to conserve gas (use at your own risk). I used the bottom portion of the tank to make a 6 gallon water reservoir for a thermal mass (212degrees) and to catch the drippings and keep the meat moist.
There is a heat distribution manifold made from 2"x2" and 2x4" metal tubing with 1/4" holes around the perimeter that gets hot enough to make additional smoke as the drippings from the meat fall on it. The smoke flavor is enhanced by a wood tray that holds wood chunks over the gas burner. The burner is from a recycled turkey fryer, and will operate for about 22 hours on a bbq grill sized tank of LP gas.

Nice, I'm planning on using the Old Gas Water Heater that I just replaced. I want to keep the thermostat control on my smoker though because the problem that I ALWAYS have smoking a Brisket or Large meat is keeping the temp correct. Charcoal has to be replaced and just takes too much work. If the water heater control can sense the temp and fire the burner from the pilot running, then it will be able to keep the temp at around 180 to 200 or whatever you have it set at. I think it will work.

@TheCabinetmaster I wanted to use the temperature controller as well, and that may work, but the water with the meat drippings gets pretty crusty and greasy, and sometimes I cook without water, and the basin just collects grease. The temp with the propane burner is pretty solid as long as it is not really cold or windy. I used one of those reflective windshield screens this year to make a blanket cover and that helps keep the heat in the cooker better.
