Ok this was a total suprise I went home for Thanksgiving and my dad built this rig for my brother and I to compete with. This was built from scratch the only thing purchased was the trailer. All the other parts he rummaged from around the ranch and around our small home town. Working for an oil field company he gto the pipe for free and it was virgin pipe never been used. Still needs a difuser between the firebox and the main chamber and to eal the doors properly add a few themometers and we will be in buisness. The Red Panel goes out 45 degrees for shade on both sides.
