Anyone have any experience with them? Or other suggestions to add a
toilet without adding plumbing? (Aside from chamber pot, LOL!)

A friend had a similar gas fired one in a vacation trailer on his land. It
worked. It has been some years, but I don't recall any odor from it, at
least inside. Considering the cost, I'd certainly look for a way of
plumbing a standard type of toilet, or one with an effluent pump if need be.
