Hi - I've not owned a Trailmanor, but I've been around them in campgrounds. They are somewhat more complicated to setup and take down when you get to a campsite. I believe they are lighter in weight than a comparably sized HiLo. And, everything I've heard about them tells me they are prone to leaks if it rains. If you look at how they're designed, you can see how they would leak easily.
As I recall, the Trailmanors I've seen do not have a genuine toilet that empties into a black tank. They had a "cassette" style toilet.
