Extended boondocking stays are such a cool thing, and we have always enjoyed and prefer them. But there are several things that must be considered. Our 500 watts of solar and Yamaha 3000 watt generator, pretty much take care of power. The water tank and pump along with the 35 gallon blueboy for blackwater ,take care of the tanks. Here is how they look on the small utility trailer.
When we exercise reasonable water consumption, it in turn reduces the amount of waste water. We make a short trip to dump the blueboy and fill the water tank about ever two weeks, sometimes a little bit more or less. When the weather and water gets warmer we will bathe in the lake, which really conserves freshwater and grey water tank capacity.
