So, I am not sure where to post this maybe a different site all together but just want to see if anyone had any knowledge for me. For my smoker build I am turning a 20ft boat trailer into a flat bed/bbq trailer. My question is what would be the recommended material to accomplish this? C channel? 2in 3/16 L? 2" square tube? The overall width will be close to 8ft, just inside the width of the tires. the length of the flat bed portion will be approx. 9ft from the rear of the trailer. the rest will be used for the BBQ part? Any help will be appreciated Thanks in advance!
