As for now I have a portable Camco toilet with 5.3 gallon tank. No smell or leaks, using it almost for two years (after my bucket+chair system).
Just remember that for public health reasons, a human waste bag should not be dumped in the trash-even if it is diluted with kitty litter. I know, no one policies this, and I realize infant diapers go into trash cans, but it is still way less than ideal disposal.
Though you can bury biodegradable sacks in open countryside. They usually contain a powder that turns liquid waste to solids. These can then be buried.
