Here are the pictures, which speak volumes for the functionality. As for the guts: Steel 55Gal Drum 120V 15A input to work on nearly any household outlet. Dual PID feeding control to a 25Amp SSR. (second PID used as alarm-limiting relay) Dual PT100 RTD Temperature probes Output to a single 1000W Electric coil burner with heat-fuse and thermostat bypass 6 qt cast iron pot for heat retention and woodchip holder Two layers of Reflectix insulation: Single 25ftx24" roll. Two 22" grill grates with stainless steel mounting hardware Custom caster platform for easy maneuvering from storage to cooking location I got the rig up to about 190 Degrees F before I put on the Reflectix Insulation, after that: hits 225 F in less than 12 mins (my favorite pork shoulder temp, have gotten over 250 when testing). Hold temperatures, with +/- 0.5 degree accuracy, indefinitely. Have smoked 5-6 full shoulders, 4-6 racks of ribs, more sausage than you can stuff a snout with, peppers, corn, and other tasty items, all with simply perfect results. I have a Bill of Materials if you are interested. All told, it costs about $238.15... give-r-take what you have lying around the house. Any Questions?
