This is what I got for $100 24" x 84" on boat trailer No separate firebox. Well used by former builder/owner. He needed money. Rack supports need re-welding. Right side was used as firebox. He blocked right stack to achieve the proper airflow to the left side. It's tacked to the trailer. Plans at this time are to install a firebox tank in the back with the appropriate sized hole and heat baffle. Questions? Comments? Snide Remarks? All are welcome. Remember though, I'm tight as a stripe on a nine-ball.
