How much liquid will cover the bottom of my black tank?

Just in general I know tanks are not all the same size but I have a 21' HTT the black tank is 22 gallons. I want to keep some liquid in there sloshing around when I travelling (after dump) how much...

today 20 seconds filled my 2 gallon jug so 2 minutes is a good amount. I figured 5 gallons would be a minimum but of course that puts me 1/4 full.
