Hubby and I have been considering the same thing and I've been looking at B+ RVs and everyone that I have seen have something I love and something I hate. One that comes with a Murphy Bed looked good, BUT it had an outdoor entertainment center. I rarely use the inside entertainment center so outside would be a waste. We want one with a slide, that is a given, that gets decent gas mileage and that's about all.
Since I asked about the same question earlier, I got a lot of naysayers saying they were to small to do any extensive travel as a couple, and then I got some who loved their B and the ability to go anywhere anytime and park anyplace (which is our main reason)plus good gas mileage.
Planning to go to a local RV show next month and 'window shop'.
So if you find the perfect RV please let me know.
