I saw a pretty comprehensive video about RV composting toilets on YouTube and my thoughts on the matter went from no to hell no. I personally can see no reason to ever switch over a trailer that already has black and gray tanks other than possibly someone boondocking for extended periods of time who has other ways to deal with gray water. But for the vast majority of trips where you need to replenish fresh water and dump the gray tank it just doesn't make sense. In that case, it's just one more handle to pull at the dump station.
