I am a newbie to this and am wondering if there is anyone here that has built a Vertical 250 gallon oil barrel RF BBQ/Smoker? And if not can you help out to get started? And can someone help me verify the calculations of the equipment that I have so that I am sure that the numbers that I have found is the same as what you find? The 250 Gallon Oil Tank standing vertical is 27.1" wide X 44.6" high X 61.7" long. The stove I have is built in the shape of the oil barrel except it is smaller. It is built with 3/8" steel, it measures 24" wide X 30" high X 27' long. The door opening measures 11.25" high X 18.75" wide. The original draft size is 4.25" high X 9" long. I can post pictures if this would be more helpful.
