No RV toilet paper.
No septic perfumes and when you're done, you're done.
There is no "cassette" full of poop that you have to wash out.
With this kind of toilet setup, you can throw away anything because it's going in the trash. You can throw anything in that won't poke a hole in the bag (like diapers, feminine items, baby wipes, beer cans... ).

If you put six 13 gallon kitchen garbage bags inside of it. You use the toilet, take off the toilet seat, tie up the bag with as little air as possible and drop it back into the toilet. This solves the condensation problems and 89% of the smell. When I say tie it up, I'm not talking about the drawstrings, I wrap it around my hand and I tie a knot using the whole bag like it was a rope. When you use it again, that bag is inside of the next bag you tie up. Then the next one and then the next one. Double bag the last one that goes in the trash.
When you are done you have a fairly solid bag that doesn't act like a bag with 2 gallons of yellow water. They sell $2 bags for these things that is just a trash bag glued to a ziplock bag. 13 gallon garbage bags cost about 15 cents each. If one leaks you can see it leaked into the next bag and you can just knot that bag as well. If it leaks into the bucket, you can wash out the bucket.
This is the best solution for the money (for me). I could give you pictures of the knotted bags but I assume this description paints the picture well.
If you don't knot the bags like I described the toilet seat and lid get covered with condensation from inside the toilet. I will leave one for 15 to 20 minutes for other people to use before I knot it, but not longer than that. If it does get condensated, I wipe everything down with two baby wipes and throw them in and then it's ready to use. Don't forget to wipe under the seat. That's a lot of surface area and the condensation is trapping smells.
I have buckets from all the big box stores. I started with a Lowes bucket because it's a neutral color

I dropped a 10 pound barbell weight inside

I found a smaller bucket (Menards plaster bucket) that fits inside well. I chopped off the top on a table saw. I then scraped the inside of the cut edge with a box cutter to remove any sharp edges that may poke a bag.

I dropped it in and stepped on it. If I want it back out, I flip it over and bang it on a hard surface till the weight pushes it out

I fill it with six 13 gallon bags and slap on the lid.

This is another toilet I use for camping. The tent has more room so I have a seperate bucket with a lid. The lid isn't sealed. It's just set on top to hold in the odors. The used bags get dropped in there and then get bagged later for disposable.
