This is the midsized model Gravity Fed Smoker from the Stumps line of smokers. It can hold quite a bit of food. It's well insulated, easily moved on rollers and produces more than enough smoke to satisfy even the most Smoke addicted.Food Capacity:- 12-28 racks of ribs- 8 briskets- 12 boston butts- 24-28 chicken halves.This unit burns fuel slowly. So slowly in fact that I was able to complete a 14hr smoke using barely 7lbs of fuel. Small chunks of flavored woods go in the ash tray underneath the chute. It works by having burning embers drop on to the flavored wood chunks to provide smoke. It can be used without any added devices however, with a DigiQ Qx2 or other apparatus, this unit will maintain a set temp no matter the ambient temp. I was able to light this unit at -7F and hold 225F thru the entire smoke without adding any fuel. It is a heavy beast. Over 400lbs so lifting will require a forklift or several of your strongest friends. It is also competition grade so if you're entertaining going pro, this unit is the one for you.I would absolutely recommend the Stumps XL Baby to anyone. Its big, its very good, and it isn't cheap. It will represent quite the investment however if you're able to meet the price, this smoker will not disappoint. The Stumps Baby is less expensive but no less the gravity fed smoker the XL baby is. Smoke On!.
