Looks like I'm late to this party but thought I'd throw my .02 in anyway for future reference. I take what Chis has listed under Holding, Storing & Reheating
Barbecued Meats to the extreme and probably is overkill. I have a huge pot that I fill with about 5 gallons of water, bring it to a boil then dump the boiling water in my cooler, close the lid and let it sit until I'm ready to use it, say up to 1 hour prior to removing meat from the WSM. Right after I've wrapped my meat in foil and a towel I dump the water (be very careful as it's scalding hot), dry quickly cooler with a towel, line with towels and I'm ready to roll. Will keep your meat nice and toasty for hours.
