So that's 38.5- 44 quarts of water for your mash, plus the 22 lbs of grain you're using, all in a 48 quart cooler. Sounds like trouble. If I were you, I'd mash a bit thicker (~1.25 quarts per lb.). That gives you 27.5 quarts of water, leaving a more reasonable amount of room for the grains, which you'll need to stir as well. You should be able to do this with no problem, but I think you'd be best off mashing thicker.
