I just got a GOSM 3405GW. I've done a couple smokes on it and have noticed that it seems to leak juices from the bottom of the unit. This is due to nothing in the bottom of the unit to catch drippings that fall behind or to the side of the water pan. I've considered lining the bottom of the unit in foil to prevent drippings from leaking so I can use the unit on my deck instead of on my concrete pad. Has anyone else done this to keep the drippings from leaking all over the place or what other tricks have you used?
