I've been looking around here for a couple days now and have found great ideas and information. After a couple years with my propane cabinet and 18.5" WSM, I'm ready to step up my game and enter a local competition that is starting to happen every year. My brother in law can get me a 250 gallon propane tank (valve removed, ready for scrap) but I have a feeling that's going to be overkill for me at this stage, and too big of an undertaking to get ready in time. What size would I be looking at to do maybe 4 pork butts, a couple briskets and a few racks of ribs at one time? Preferably doesn't need to be built on it's own trailer, but could be moved around with a half ton. I like the design/concept of the RF rigs and am leaning in this direction should the size allow. Thanks in advance for any input on rig size.
