I too am intrigued by the upper living room. However, I think I would really miss the big rear window in our 3400. We park quite often so that the window (we) are overlooking the ocean, or a bay, or a forest, etc. But, that upper living room sure looks cozy. Hmmmmm.........
Mike, which RR do you work for? I'm one of the volunteers here in Portland that work on/operate the SP&S 700 steam loco. We were in Sand Point with it in 2002.
