Cassette Toilet vs Conventional RV Toilet

I currently have a conventional toilet/black tank, but I would much prefer to have a cassette in my TC!
I do a lot of extended boondocking… 2+ weeks at a stretch. I carry an external waste tank which is a hassle to empty. If I had a cassette toilette I could dump in any porta-potty, pit toilet, or gas station toilet. I'll probably go through the effort & expense to install a cassette toilet sometime in the near future.
Cheers,
