I’ve seen numerous videos where women say they love their Air/Nature’s head. The only thing they mention is having to scoot a little forward to pee.

 

Women can absolutely separate. My wife doesn't have an issue with our Air Head. They don't go in the exact same direction unless there is something abnormal about your wife. I highly suggest she educate herself on composting toilets as you won't regret that decision. My wife just said last week, "I really wasn't sure about this toilet and was ticked you spent so much money on it, but it turns out its perfect".

 

One other thing I have learned using the cassette toilet is that it also works great for disposing of gray water. I have a 15 gallon gray water tank installed under the Transit floor. It rarely gets full.

If I am someplace without an RV dump, after emptying the cassette tank into a restroom toilet, I then use it to drain the gray tank. I place the empty cassette tank under the gray tank drain valve and transfer the gray water into the cassette. The gray water is disposed of into the restroom toilet. Besides properly disposing of the gray water, this also has the benefit of rinsing out the cassette tank.

 

I am experimenting with a 5 gallon bucket and a pool chlorine tablet for everything. So far results are reasonable.

 

On my second camper I installed a Thetford cassette toilet and use it as designed. It was fine, but emptying it is no joy. On my third camper I installed another Thetford cassette. When I first used it, it was deep winter and I didn't want to worry about freezing, so I put a bag in it. I have been using bags ever since. Never even put water in it.

I also have a Thetford cassette toilet and am very happy with it. I use it year round with a little RV antifreeze and water in the holding tank.

I'm curious about where you have access. Did you go with an external wall on the van to place the cassette door? I'm wondering about having the cassette toilet slide out from under the platform bed. That would mean designing the garage space so it isn't too bad to crawl in there every few days to access the cassette.

 

I also have a Thetford cassette toilet and am very happy with it. I use it year round with a little RV antifreeze and water in the holding tank. To avoid any smell, I only use the holding tank for urine. When the toilet must be used for solid waste I use a bag as described by Kenryan. If I'm unable to immediately dispose of the bag, it is temporarily stored in an airtight ammo can. This method keeps all odors out of the van but odors do escape the bag causing the ammo can to stink but that's easy to clean and deodorize. If I were the only person using the van, I'd stick with Msnomer's system but my daughter is more comfortable with something that sort of resembles a traditional toilet.

 

My campers weren't vans, so it was very easy to put the access in a wall. But for a van I would not recommend that. I would place the toilet for easy access. It is a clean system and pulling the tank inside would be no big deal. An ideal spot seems to me to be adjacent to the side door, where you could pull the tank while standing outside, without putting a big hole in the wall of the van. The unpalatable part of dealing with the toilet is not pulling the tank, it is dumping it.

 

I just picked up a new Camco 2.6 gallon that will be stowed under the bed when not in use. I used one at our cabin for years. Simple, functional, durable and only cost $66. Seemed like a better option than the more expensive and complicated dometics that had mixed reviews.

 

I have had two Therefords. The first was an electric pump model, included in the van build, which worked faithfully for four years and then I sold the vehicle. We were a family of 4 and used it as the exception (not the usual restroom) and at night. No smells or difficulties.

Now the kids have gone so we are a family of two and I bought the Thereford 365. Again, it will be used as the exception and I am expecting that it will work as well as the first. At times, it is difficult to find an RV dump so I prefer to use the portable dumping into a toilet method. We usually emptied it when it was half full so the weight wasn't a problem.
