Ok - I have many questions. I have been smoking for many years on a New Braunfels look-alike. Now I want a big trailer mount smoker. LOL. The local lodge has decreed I am the bbq master, and now they want to sell some ribs for a fundraiser and we are having a bbq dinner in a few weeks. Awful hard to cook for 400 on such a small smoker - but we have did it before. Anyway - the only thing I am pretty much decided on is a reverse flow. I really would like to build a Lang clone, although I saw the build of a bottom fired reverse flow pit on this forum - and thought it looked pretty amazing. I am unsure how that would scale up to something much bigger though. I already have some heavy wall 36" pipe donated to the cause (2 sticks at I think 6'). I would love to build something big enough to hold 100 slabs of ribs, but I am thinking 10' long would be about the best size. Tell me what you guys think - any ideas, or thoughts would be appreciated. This build will take some time - it's a bunch of volunteers and we are trying to do it on the cheap (all of our money we make goes to scholarships and benefits for others in need), but I do promise pics and updates.
