Big Ass BBQ Pit Build! Fully Insulated! DIY

I built a very large, fully insulated, direct heat BBQ pit this summer. This is the build video. The cooking surface is 5 feet wide, and 3 feet deep! 2" of insulation all around besides the doors having 1" of insulation. Total weight is over 1,400lbs! Hope you like the video. If you're in the market for a pit email me at [email protected]. Build details are below.
