Hey Mitch, I have to agree with not using water in the pan. I wrapped the pan (both sides) with heavy duty foil, filled the pan about 1/3 full of clean sand and then put two layers of HD foil over the sand, pressing the foil down onto the sand. Good luck, Bro, you've got a great little smoker there.
