I haven't had the WSM long enough to try, but I don't think I will either. Generally when I go camping it's either backpacking or car camping but hiking all day. So I'm not going to be able to monitor the smoker. What I plan to do next time I go car camping, however, is bag up a bunch of pulled pork, ribs, and brisket into vacuum bags and take them along with a bunch of homebrew. I can heat them up in hot water either over the camp fire or on the stove. As for carrying homebrew, I bottle up a bunch in 2 litre PET bottles (soda bottles) with some special caps I made. I fill them from my kegs and then blast 30 PSI of CO2 on top to keep them carbonated. Every night around the fire we have draft beer :-D
Life is indeed good.
