So I just got a Chargriller Duo with the SFB. Try my first smoke the other day (bacon wrapped chicken breasts) without any mods. I was using a digital thermometer with a probe for the grill and one for the chicken. Considering as soon as I put the chicken on the sky's opened up and it downpoured for hours, the chicken actually came out not bad. Today I made some mods (see pics below). Ordered a baffle plate for $74 from an online smoker store. Sealed all holes with food grade/high heat silicone. Also put a mix of nomex tape and high heat fiberglass rope around lids of smoker box and smoke chamber. Used a rolled up piece of aluminum duct(non galvanized) to extend chimney stack straight down to just above grate level. Last thing to do is put dual thermometers on each side of grate at lid level. Hoping these mods make for a nice consistent smoke temp. Thoughts?
