Dear Brewer,
Let's talk about definitions, OK? I call it dry camping when I am in a town. In the forest, desert, etc., it is boondocking, because I am out in the boondocks (away from where people live).
One of my webpages is about Dumping holding tanks. Take a peek at it, and this may help a bit.

Taking a shower everyday is just too much for being out in the wilderness, unless you have a water source nearby. Like a creek. I always take very brief showers. My water tank is only about 35 gallons. Gotta be careful.
Propane during the winter lasts about three weeks. During the summer, maybe 4-5 weeks.
My kitchen is not a galley. Be careful, you might hurt MsTioga's feelings!
It is a full fledged kitchen, and is just plain wonderful for cooking. I have prepared meals for four people in my kitchen, with no problems.
Quiet for sleeping? Depends on where I camp. Here in Santa Rosalia for example, it is soooooo quiet at nite. Except maybe when the wind is blowing really hard.
Bye for now,
George
