150 Gallon Reverse Flow Smoker with Insulated Firebox on 5×8 Trailer

Description

When pitmasters search for the biggest smokers that still offer mobility and efficiency, this 150 gallon reverse flow smoker stands out as a serious contender. Recently completed just a couple of months ago, this unit combines fresh craftsmanship with heavy-duty materials, making it ideal for long-term use in catering, competition, or large-scale backyard cooking.

The 150 gallon reverse flow cooking chamber is engineered to promote even heat distribution from end to end. Unlike traditional offset systems, the reverse flow plate forces heat and smoke to travel the length of the chamber before circulating back across the cooking racks. This design reduces hot spots and delivers more uniform temperatures across both racks.

Inside the chamber, you’ll find a two-tier cooking system:

• Bottom Rack: 22” x 35”

• Top Rack: 15” x 35”

This layout allows for multi-level cooking, giving you flexibility to manage different meats or temperature zones simultaneously. Whether cooking briskets on the lower rack and ribs above, or separating poultry from red meats, the configuration supports efficient batch cooking.

The fully insulated firebox measures 22” deep, 22” tall, and 20” wide. Its insulated construction dramatically improves heat retention and fuel efficiency. Compared to non-insulated fireboxes, this design maintains steady temperatures with less wood consumption—critical for overnight brisket cooks or high-volume BBQ events. The airflow controls allow precise management of combustion, producing clean blue smoke essential for professional results.
