if you're having trouble getting your rub to stick..guessing this is your lack of bark issue??? (brown sugar in rub = bark that other seasons get trapped in...got my mouth watering), use a yellow mustard layer first. you don't taste mustard once cooked and it gives the rub a medium to stick to.

yes on room temp before cooking, yes on night before rubbing though not necessarily plastic wrapped, in water pan use apple juice, apple cider vinegar, apricot nectar and or pineapple juice and water mix. can also put that mixture in a spray bottle and spray it anytime you open the door (if you're a peeker).
