I realized recently that I have need for a toilet on a regular, sometimes daily, basis. I hadn't considered this in regards to my truck camper until very recently. Duh. How silly of me. The first thought that comes to mind is a composting toilet using coffee grounds and such. The next thought is a urinal that can be routed straight out to the ground. I'd only ever want to do that for short term, discreet stays, not long term where the smell would become a problem. I once made a urinal on the second story of a barn I used to have by hooking a funnel to a garden hose and routing it downstairs and outside. It worked great. Used to flush it with a Gatorade bottle full of water. Worked very well indeed. This might be useful in my truck camper to stop the composting toilet getting overwhelmed, and make it easier to pee many times a day like I down when active and chugging water all day. Trying to figure out how to integrate something like a composting toilet and a urinal into such a tiny space. I suppose I could just build a dedicated bathroom. Would be really nice for camping in urban environments when it's too cold an/impractical to find proper toilets and such. I think I may very well include a bathroom. More thoughts on this later.
