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 ...
We have 55 gallons fresh water in our Class C. Can easily go 5 days (the limitation is the gray water). We shower daily - brief navy style. We are very conservative on how much water we use in dish washing having developed a very systematic water conservation approach. I can't wash my voluminous hair in the camper - need to rely on campground showers for that.
