We have essentially done what you are contemplating. Be aware that a B is fine for two people, but a mite crowded for three. The third person bed, at least for the Roadtrek, is sort of a make-do. Take a look at the models and have your daughter try out the bed. It's narrow and probably a little firm. There are a lot of adaptations and compromises that need to be made going from a "large" RV to a small B. A lot less "stuff", limited space to move around but compare that to the advantage of parking, fuel mileage, and taking advantage of all the latest technology. A trailer or hitch box on the rear adds room, but lessens the choices for parking or sightseeing. We decided to live with what would fit inside in the drawers and shelves. Ordering new can be frustrating for the wait time, but Roadtrek was 7 weeks, Pleasure Way is much longer, some say it has taken most of a year. Our travels are similar, but we also intend to stop at a motel once or twice a week to shower, wash clothes and perhaps enjoy stretching out (grin). We usually would eat breakfast and a light supper in with a midday "dinner" at a restaurant, which also allows us to enjoy local cuisine. This certainly helps with the food storage and shopping.
