I've seen a picture of an '81 Excella II in that length several years ago. If I remember correctly, it had a rear corner bathroom. It had the blue vinyl stripe down the side and had an upscaled interior just like the previous Excella 500 line. The picture of the one I saw was for sale and looked like a nice trailer. I imagine it is a dream to tow.
