I have removed the toilet on all 4 campers, and never installed on two.
Black water is gross, and dumping it and dealing with it is more gross.
I poop in a bucket with a 3 cent trash bag that I used the day before as a trash bag. As a man I can manage to simultaneously squirt the other side into a p-jug so the bag is not full of liquid. If it is full of liquid it has never been an issue and I have never had a leak.
The bag can be stored as trash.
Gas stations, I have found, have convenient trash cans at the pump.
I am not someone that needs a magazine and 20 minutes of my day to discard my waste... Im in and out in seconds, so I do not need comfort, a bucket is fine.
Not having that dedicated location for a toilet means more storage room. Not having a toilet means no splatter and no stink.
I have owned and used for years the portable flush toilets. They are easier than a black tank, but you still have to carry the little black tank and dump it, then rinse it. Ick. I just prefer the cleanliness of the bag.
The composting toilets are gimmicky as far as composting. I doubt anyone leaves that stuff in there long enough to make compost. At best they are managing the smell and maybe drying it out.
A crow taught me in the desert that if you leave the bag open during the hot dry desert day that the little log will dry out and not have any odor. Does not work on the East coast though.
If you have female company then they do make a real toilet seat that fits on the bucket.
Do not defacate in or near a stream. The forest wants you 200 feet from a stream even for tent camping. Be far enough away that your waste cannot find the stream during a rain event.
For families the bucket and bag might not work as well.
You can use a bucket still and just cover it with saw dust or whatever and move bucket outside when not using. Think outside the box..
The reason RV manufacturers are not using composting is because RVs are built to appeal to the wife, not the man. Cheaply built yet pretty campers sell bc the wife likes the curtains.
