@boonie, there are a couple of choices to make about using the toilet, and we have used both. Depends on your personal preferences and the circumstances. Just over a year ago I posted a semi-humorous, kinda tongue-in-cheek thread entitled "STRANDED" in which I described us having to use rv antifreeze with toilet use. In this case, we did an emergency blow-out winterize job on the t@b, but for 16 days had to continue to use the toilet. We had a few gallons of rv antifreeze with us due to the time of year we were travelling. We found that adding equal parts of the antifreeze in the toilet bowl to human liquid, nothing froze in the black tank, but at 7,000 ft altitude,  about 10°F, the tank contents became slushy. We increased the rv antifreeze concentration to 2 parts antifreeze and 1 part human liquid and that was good until we were able to be on our way, at -10°F. We were about 1 1/2 miles from a Walmart. It was easier for the DH to walk there and carry a gallon of the rv antifreeze in each hand back to the trailer than to carry a large bag/ container of cat litter that distance due to weight or volume. However, when prepared, and not stranded, the double garbage bag and cat litter routine is usually less expensive and more convenient. Using the antifreeze, you still have to have somewhere to empty the black tank. Using the cat litter, you bag the litter and your waste and dispose in a regular trash receptacle. Double bag in the toilet bowl for assurance that the bag will not leak or puncture and the package is safe for disposal. If traveling and not experiencing temps below zero, with the possibility of emptying your black tank every 5 or 6 days, I find that method easier. Personal preference. But if preplanned and traveling to a destination, to make time and more miles faster, the double bag/cat littler method is favored. If money is of no concern, several commercial products are available such as "wag bags". Again, personal preference. Good luck with all details travel related. It's all part of the adventure!

@boonie I use the litter box method during winter when I go play in Ladybug in her shed. Saves running back and forth to the house in the snow! Once I’m out of litter I’m switching over to pine pellets sold for pellet stoves. Much cheaper and works well for cat boxes so I figure why not my set up? Again, personal preference, but hey, it works! 

What bags work best if used with the tab toilet for late season Also, besides kitty litter, I’ve heard of people using a gel product.  Some bags are EPA approved, that must mean they break down over time.  The clean waste portable toilets sell kits and their additive is supposed to break down things, while also solidifying liquids.  This bag is one use unless you add more gel stuff.  We’ve really only have been summer campers and would like to extend the time after we would be winterized of course.  

@TerryV6, I have used Double Doodie bags and if the gel is not included, it can be bought separately. See Amazon. 

I like this idea of pine wood pellets. Cheaper, lighter, etc.

However, with a quick search, I can't find anything except cat litter.

Are they available for pellet stoves? 

@ChanW yes, same ones. I have a neighbor who is a cat whisperer/rescuer and she uses only the wood stove pellets in her litter boxes. Her house doesn’t smell of cat urine at all, and she has at least three litter boxes and I have no idea how many cats. Let’s just say many cats. Pellets are cheaper than litter, and now there’s a litter made of a similar product. For those of us who live with four seasons getting the pellets shouldn’t be a problem. Pellets are also handy to burn in small wood stoves, like the Flame Genie. 

@ChanW I think these are two possible links for pine pellets...I've used them when I was taking care of rabbits at a farm sanctuary, their urine smell could knock me over and make my eyes water, before I took the initiative and bought the pellets. They are also used in horse stalls. It never occurred to me it would be great for "dry" camping.

Ah! Thanks all.
This sounds like the way to go, rather than collecting a half-froze black tank of slush (oog). (We do have both Lowe's and TS relatively nearby)

We have been pondering the (new to us) knowledge in this thread. Please excuse the naivety, how do you properly dispose the bags/contents? Regular trash, or something more involved?

Regular trash, as you would any other cat litter, dog poop, or baby diapers. Best to double bag for the safety of the person handling the trash.
