I have a 40 gallon fresh water tank. We took 2 quick showers, a few toilet uses and a small dish washing and my tank was showing empty. What is the average dry camp water use? Seems to us, 40 gallons ...
I think washing dishes uses more water than navy showers. Water is the limiting factor as to how long you can dry camp. I have a 60 gal FW tank which will last two people 7 days with out too much effort. If more people come I will use a 5 gal jug outside to wash pots and pans and silver ware, and use paper plates just like tent camping.
