Long time Lurker First time poster..Just wanted to show off my baby!! Gonna do some catering in NE and give some Great BBQ ! all made out of 1/4 plate ... The Firebox has 2 layers of steel with 2400 temp insulation in between ..Main chamber racks (2) are 5ft x 3ft capable of handling 2 whole hogs 250lb each ...the vertical smoker/warmer (depending on if the flute between the firebox and vertical is open or closed) (3) racks are 3ft x 2ft..total cooking space is 48sq ft i think =)... all mounted on a bobcat trailer with space to mount a 3 bay sink , hand washing sink, hot water system and a fridge ......whats nice is i have a plate to close off the main chamber so at home or for smaller functions i can just use the vertical ..the frame for the roof is heavy duty with awning that folds down to be a half wall that i can advertise on...not sure what to do with the rooftop yet. I threw in a couple Butts, ribs , chicken and sausage(i put hooks in top of vertical smoker to hang sausage)..smoker smokes like a locomotive!!!
