Reverse Flow 1000 Gallon Monster

The 1000G Grande is a large-scale, heavy-duty reverse flow smoker built by Johnson Custom BBQ Smokers. Constructed from ¼” to 3/8″ steel throughout, it features a 16-foot main cooking chamber (19 feet total length) mounted on a brand-new 18-foot tandem axle trailer. The smoker includes four counterweighted cooking doors for easy access and offers flexible rack configurations:

• 2 racks per door ≈ 68 sq ft cooking surface
• 3 racks per door ≈ 94 sq ft
• 4 racks per door ≈ 146 sq ft

Each rack measures combinations of 36”x36”, 36”x33”, and 36”x24”. The reverse flow design uses dual adjustable baffles to eliminate hot spots and ensure even heat distribution. Heat and smoke are drawn through two 8-inch diameter, 5-foot tall stacks positioned at grate level to improve efficiency and reduce wood consumption.

The firebox is 36”x36” with four 6”x4” vents for optimal airflow. Additional features include:

• Spring-loaded handles to prevent burns
• High-temp (1200°F) paint finish
• Flat-strap door seals to minimize heat loss
• Built-in thermometer and perimeter shelf
• Pre-seasoned with pecan wood by the builder

Optional upgrades include stainless steel racks and custom plasma-cut logos or ranch brands on top of the unit. Chrome wheels add $600. The entire rig is designed for commercial-grade durability, efficiency, and consistent performance—ideal for serious pitmasters or catering operations.
