Well, I got to meet my neighbor, Sonny, the day before yesterday. He's maybe in his late 30s, and is a roofer. He's married, and a woman (that I presume is his wife) has been there the past two nights, but I haven't met her yet. I did show him my bus, and he did show me his. He just bought it from his in-laws, who used it only as a weekend camper, so while it is converted for living, it is not converted completely for full time living: it has amenities, but they are configured for temporary accomodations. He wants to make some changes to it for full time living. The primary changes that he wants to make are to add a shower, a hot water heater, a water pump/storage system (city-water hook up only), and plumb a toilet (porta-potty currently).
The layout is (from front to back) living area; kitchen area; bedroom; and bathroom. I think it's a very nice layout. He shouldn't have any trouble making the modifications he has in mind.
