I think you have basically said to leave it for 3 weeks after a trip for decomposing, but what if you don't have 3 weeks of no use? eg a long tour/trip, or a series of short trips with short intervals between?
We recommend eight hours after last use before emptying. Using fulltime it will not be all composte: if for example 1 week, then 5 days again , then maybe a month before use it will go many weeks before needing empty. When using fulltime ideally emptied into a compost pile, or put into a plastic bag, in a bucket open with a ventilated lid it will finish composting, 30 days to 6 months depending on temps, the warmer it is the faster it composts. If just put into a bag and thrown in a rubbish bin it will finish. With Part time use: it may be 4 to 5 months before emptying. Our users guide described this properly.
There some five videos by Jason Wynn in a Fleetwood motorhome that have used this toilet fulltime for a couple years, also content on their website: www.gonewiththewynns.com The videos are very informative.

I like the water savings means we could stay longer when remote camping most of all but it's the how to responsibly handle the waste that I'm not sure about. I did watch the Gone with the Wynns series - actually I'm a paid subscriber of their channel...
Just looking for some local advice before I put one in the budget...
I just have the normal Porta Potti in van.
With a toilet seat and lid under one of the beds.
My spare table as per Avatar Chuckle.
Anytime we stopped at fishing spots etc and stayed for a while.
6 in Auger and bag of lime did us.
One van with shovel. one with Auger. one with lime bags.
Just back fill hole's when leaving.
Funny though.
I've been vanning for over 50 yrs.
Haven't lit a fire or ran a barby outside, Of ANY sort for over 25 of them.
But when we did. we always set in a dugout scoop in ground.
and shovelled a bit of lime over remains b4 levelling it off.
So any remains would be absorbed and the wildlife tends not to dig it up.
and to contain it better from windblown sparks etc. (Army training.
contain b4 deployment)
I have a porta pottie and a home built composting toilet.
The porta potti is in my bus for compactness and conveniance but it is smelly and unpleasant to clean out and empty.
My advice is to get a bucket and put some slightly damp cane straw and a hadfull of rotting leaf mulch in it. Just make sure the damp faeces is covered in straw or sawdust. Just enough to take the shine off it is enough. I was astonished at how odour free it is. HOWEVER it mustnt get moist enough to allow the air to be excluded from the process or it will got sour and start to smell. You might then makeca decision to get a more dignified comercial unit. At that point. They are pricey but they look great and are fuss free.
I am also looking for a good composting toilet and now I'm choosing from both https://www.amazon.com/exec/obidos/ASIN/B009Z7EKIC/ref=as_at?creativeASIN=B009Z7EKIC&linkCode=w61&imprToken=YxgJAlEJkS9VBw27oLdEXQ&slotNum=0&tag=ventlessr-20 and https://wisepick.org/best-composting-toilet/ , maybe anybody used it (or something others) and can recommend?
