I have to agree with Canonman, but then we live in the same western area. Camping in our National Forest "campgrounds" or dispersed camping pretty much requires carrying full tanks and I
have for 20 years over some horrible roads. Because there is limited resupply water available we have learned to get by on about 10 gallons a day. Many of our National Forest sites are also tent only or only large enough for pop-up etc. You can bet that all of their bathing, dish washing gray water, etc. ends up on the ground. If you have to drain of some gray water, watch what you put down the drain, put a filter cloth over the end of your drain hose, and spread the filtered gray water over a dispersed area. You should be fine in a sparsely populated camping area.
