I'm not shy about asking people questions when I'm at a competition, or on here for that matter as Scottie likes to point out. I've had people tell me that they won't tell me, and that's fine. I've also had several people share some nice tips and ideas.
I don't consider that cheating, or shigging, or whatever, because I'm upfront about it. It's not that I'm trying to copy other people's ideas, but I like to bs about bbq and my wife can only take so much of it. I'll share what I know, which isn't that much unfortunately. I'm relatively new to the bbq world and am trying to figure out as much as I can. Hell, tell me you put nacho cheese on your brisket before applying the rub and I might just try it, albeit at home.
As for working in trailers, putting up walls on a tent, etc - I say the more shelter from the wind, rain, bugs, sun, etc. the better. If I had an enclosed trailer large enough to work in, I'd be in it. For now, I'll take the costco canopy.
