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 ...
40 gallons would last us about 5 days but we don't shower every day. We have a 100 gallons in the Moho and it lasts us 10 days plus or minus. Every one is different in their habits. You will get better at conserving water.
