To eliminate the wind factor with my smoking I built this shelter out of 1 & 1/2 sheets of cheap plywood and 8 - 4 " hinges . For the extension on the exhaust I used a piece of 6 " heater duct pipe . After it was built I tried it out the next day , the wind was blowing alittle with gusts about 8 - 10 mph. The inside temp was a constant 220 -230 degrees and the smoker control valve was on low and the gas valve was opened a crack . ( on one pic you can see the smoke was horizontal ) When your done with it folds up to only 3 " wide for easy storeage .
