Looks all-original...has the bunk fold-out over the main bed in the back.
BUT the toilet was added after manufacture and that niche up front is not a bathroom. There's no bathing meant to occur in there and so little room you'd be hard pressed even to use the toilet that has been installed unless you are quite small, young, or thin or all three.
Still a great price IF the floor is sound. Start checking around the toilet hole as that was one of the chief weak areas.
Looks pretty good.
Glad to look at it, thanks for alerting us about it! HOpe someone gets it and enjoys it tremendously!
