Well my neighbor went and got a brinkman vertical char smoker and is having trouble keeping the temp up. I was wondering if anyone has one / are there any mods that I can tell him about to help????? It is the one with two racks in the upper chamber and the slide out water and char pans in the lower chamber with with two air dampers in each chamber. I think he needs more air flow across his coals and suggested drilling holes around the coal pan even with the dampers ......???? H E L P ! ! !
