Another piece of advice based on our build. We are a full service unit with no commisary. We boiled some noodles, ran around 2 gallons of coffee,washed hands and dishes. At the end of the day we ran out of water before cleaning all our steam pans. Filling three sinks takes a ton of water. We went with a 20 gallon fresh water tank, hindsight it should have been 30+.
