I rented a class B from Apollo last summer, and later saw an RV that looked exactly the same on RVTrader under the name "Majestic", I too googled it and couldn't find anything on it. I think you may be correct that after the Apollo rental folks are done they sell the units under the brand "Majestic". Renting the van was what sold me on buying a Class B, however I never would have bought that RV.
For me it had 2 BIG issues...
1) The toilet. It does not have a "black" tank, rather the toilet had a cassette that you have to pull out and empty. It's not very big, I could only go couple days before I had to empty it. The cassette was also heavy and hard to dump - you had to get it lined up with the hole and lift it, without spilling it's contents. Also, it did have a grey tank, which you dumped with the usual hose. So dumping was a 2 step process (3 if you include adding fresh water) and involved multiple opportunities to make a mess. Rumor has it you can dump the cassette in a toilet - although it would take multiple flushes, so that could be a plus if you don't have a dump station handy! By contrast I can go 5-6 days on the tanks in my Pleasure-Way and dumping takes a grand total of 5 min - hook up the sewer hose, pull the valves and done!
2) The Refrigerator. The unit I rented had a 2 way fridge - AC/DC only, no propane. I like to dry camp. The fridge sucked the battery dry in the 1st day and it was a constant struggle to keep the battery charged, made more complicated by the fact that I was camping in a generator free loop. If you primarily camp in campgrounds with hook ups it wouldn't be as big of a problem. I recently dry camped for a week in my PW and ran the generator once! I was driving a bit every day which kept the battery charged, but with the fridge running on propane there wasn't much draw on the battery.
I'm not sure what you mean by brown water, unless you are referring to what I know as "grey" water - the waste water from the shower/sink. In which case, see above, if not please explain!
The bathroom, other than emptying the toilet, was fine. It's a wet bath and I showered in there a few times and it was just fine!
The sleeping arrangement was as to be expected from a B. It was comfortable, but needed to be assembled daily and it could be challenging - the back of the van had benches along the sides with an aisle down the middle. The benches could be used as twin beds, but I found them to be narrow. You slide the backrest from one bench into the middle to make a full size bed. It can be challenging to get the backrest into the grooves by yourself b/c it's long and can be unruly! It was much easier to move and dress in the van with the bed "put away". I found that it was easier to get in and out through the back doors.
I ended up purchasing a Pleasure Way Plateau and I LOVE it!!!!! Although like I said at the beginning, this rental is why I bought the PW! It was easy to drive - and I'd drive 3 other small RVs over the years and the van was the easiest to drive - and park, and it was the perfect size for just me!
One thing the rental van had that I don't have in my PW was a backup camera - the one in the van I rented was in the rear view mirror and it was especially helpful! Also the rental van had an MP3 so I could listen to my iPod, I do miss that in my PW!
The things that were issues for me, just might be perfect for you! I hope you find what you are looking for and enjoy Class B ownership! :-)
