I don't have the model you are asking about, but own a Northstar 850SC popup with a wet bath. I definitely am glad I have a wet bath and used it ~3 times over the summer on camping trips > 2 nights. I should note that 2014 was my first season with a TC.
I have fairly small holding tanks and so I have used the campground facilities if they are available. At one site, the campground we were camping at had showers but they were quite a ways away. When I walked over there the first time I found that the token machine was broken and so it was nice to have an alternative.
I am a big guy (280) and so, yes, it is cramped. Even though I struggled when I dropped the soap :), there is nothing like a shower after a couple days of camping. It was definitely worth any trouble. In each case, I went to bed feeling like I wanted to stay another couple nights and isn't wanting to lengthen your stay the great thing about camping in a TC?
Good luck,
Mike
