Bring peat moss to throw in the bucket to cover your leavings between camp toilet uses. A brick of it at home depot is cheap and it will kill the smell. I would suggest keeping your liquid and solids separate, even if it means peeing in a milk jug. Construction trash bags, are thick and work better on camp toilets with less leakage.

We've camped rough, and know lots of people who lived rough off grid until they could get composting toilets set up. peat moss is crucial, and keeping liquids and solids apart will save you. Promise.

A thick comforter or will blanket to hang behind the seats will be useful when you're stealth camping to keep any light from your phone or lanterns from being visible from the outside. It's only a couple weeks after the winter solstice so it gets dark early and stays that way, so don't make the mistake of thinking you won't need a headlamp or small LED camp lantern.
