I think you're on the right track looking for a van camper/Class B. I'm assuming you're looking for something that can be parked rather easily and unobtrusively in a city environment? A Class B/van camper is really the only thing that can do that. Things you probably want to consider -- there's no/very little privacy. If your step daughter is a tween or older that may be a problem, or it may become a problem. There's also very little space. By the time you get two people, books, whatever your DH needs for work (a laptop, etc.) and possibly a laptop for your step daughter things can get very tight. Also with an older vehicle you'll want to check how many plugs are available for recharging devices.
