Water to me is the limiting factor of dry camping. The second thing is even if you can add or carry FW you still have the Grey and Black tank storage problem if you can't dump. There have been many good suggestions so far. 3 additional things that I do that help is I use a 6 gallon water container that has a spigot for coffee, cooking, washing hands, drinking and washing dishes. This I fill every other day. When I beach camp I use a 3 gal pump container with a spray head for rinsing sand and salt water off especially when camping with Gkids. And lastly in summer with summer activities like biking, hiking, I tend to use the rivers and streams to cool off. None of this fills grey tanks or uses FW from tank. The only real usage is shower for wife, my two g sons follow my lead.
