My popup has a 20 gallon freshwater tank. It also has about a 5-gallon freshwater reserve in the Thetford toilet, and a 6-gallon water heater. But we all know the final six gallons are not really accessible conveniently. I just took a trip where, upon arrival, we discovered that the freshwater spigots had all been bagged with signs saying "No potable water available." Fortunately I had already filled my water tanks before arrival (I don't always do this, though). We discovered that five of us consume about 15 gallons in about 24 hours. We ran dry our tank the second morning as we were packing up to leave. We also had a separate store of drinking water. So on a trip that started Friday evening after dinner, and ended Sunday morning after breakfast, we ran through 20 gallons in the tank, and two or three more gallons of drinking water. I carry a couple of jerry-cans that are reserved only for potable water, and they're what I usually use to refill my onboard tank. If I know ahead of time I'll have trouble finding water, I fill the freshwater tank and both six-gallon jerry cans, giving me enough water to last around three nights (if we don't take showers, of course). So my question is this: How on earth do you manage disbursed, or dry camping for periods greater than three days? How do you carry enough water? Yes, conservation is important. But tell that to my kids and wife. With solar I can extend my electrical budget almost indefinitely. With two batteries I can even go a week with no solar, no generator. With two propane tanks I can go weeks (even most of a season). But with one 20-gallon water tank, I'm running empty as the fun is just getting started. For this reason I've mostly shied away from disbursed camping. Suggestions?
