Carrying extra water for boondocking

re dumping gray water....it depends on where you are and if it's allowed (there will be signs to guide you on that)and how busy the camping area is. you have to remember that you won't be the only one using the spot. if you leave a wet soggy place in the actual camp site, someone else has to park around it.
desert areas are generally more receptive to allowing grey water, but not always.
