I tend to leave it all packed up until the next day, sometimes I pull the sleeping bags immediately, but it wouldn't be out of the question for it to stay in the pack overnight. This procrastination I believe is less about avoiding the chore, and more about not wanting to admit to myself that the trip is over. Even after I break everything down and clean it, all of it sits out for a week or so, because I can't bring myself to stuff it all back into the storage bins it came out of.
Sleeping pads after each trip I give a really good scrubbing in the shower, which I started doing religiously after I lent a pad to a friend and just put it away when he gave it back to me. Only to pull it out to clean to loan it to somebody else, and found a nicotine patch stuck to it, which discolored the material underneath very badly. I guess it was preferable to finding cigarette burn in the pad.
