Happy Memorial Day. Getting ready to fire up the smoker. 2 slabs of ribs rubbed and coated with brown sugar chillin in the fridge. Made some mods to the rub from last time. Last time had problem maintaining temps. Going to build fire on grates in SFB. Will build a fire box in the near future. Also going to flip charcoal grate in smoker body for a cheap tuning plate and use water pan as a baffle by the exhaust. No other mods. Want to see if I have any better results this time. Suggestions?
