Yep. Researching toilet options has my head spinning. All of them seem to be pretty awful. This is a problem, since one of the reasons for doing this is to be able to travel without using public (or others' private) toilets or hotels.
Cassette toilets/porta-pottis sound horrible and barely better than a bucket; compost toilets apparently have lots of issues, not the least of which is "blowback" (ick) and mucho-frequent dumping and problems with wet waste causing the composting part to fail and stink; dry flush toilets sound perfect until one reads the reviews and horror stories of breaking bags and such; Incinerating toilets sound perfect except they are expensive and use a lot of electricity (1 to 2 KW hours); regular RV toilets require expensive and also icky dumping. I've read about a biogas toilet, which seems pretty cool (composting toilet with a digester that converts pooh to gas for your stove). But that also sounds very complicated and potentially explosive.
We are of a certain age when bladders don't make it through the night and we want to park near our kids' homes as well as adventure camping, so taking a leak outside is not an option.
Any experience or advice appreciated.
TMI alert, but here goes ... (heh heh heh "GOES"). The portable toilet folds up, easy enough to use and store. I get wag bags and store them in a dry bag until I can throw away. If I have to go #1 in the middle of the night, I have a glow-in-dark Nalgene that I stash. The camping toilet can be set up in the front of the van overnight if it's really cold out. I use it and then put the bag outside until morning. And I take every advantage to use public toilets when on the road.
