I have been thinking of my air intake on my 500 gal rf smoker! Money it tight that's y I was thinking of porting a fan to fire box on a variable fan switch to force air in. Instead of cutting into the firebox to put inlets in because I'm not sure the best way to do it. My end goal is to have a cyber q guru system or equivalent wifi preferred but I have to get some test cooks on before June 16 th have my aunts 70th b day party plans are two whole shoulders and a lil pig....
