IMO, class B vans are still the best touring option available. With few exceptions, they get the best mileage in a self-contained motorhome for someone who is going to be on the move, seeing the sights. That was our choice 5 years ago, and for those reasons. We noted and accepted what we felt were the shortcomings of our Roadtrek, as a wholly self-contained option, that being primarily the interior space restrictions, which caused the converters to come up with some innovative ways of trying to provide all of the amenities of the larger classes. Some of those innovations simply haven't worked for us over the years, and we decided to try a (slightly, I hope) different way of travel, that we hope will give us the best of both worlds, touring and destination, with almost 50% more usable interior space, and full residential style amenities, in exchange for the mobility and some of the fuel economy.
I'm still amazed at the few people who actually "full time" in a class B, although from what I can tell, they aren't entirely full time. Most have a docking station or home base somewhere, like the rest of us, where they rest and relax and maintain their vehicles for a short while, after months on the road. But it's close enough. I hope we can be possibly 1/3 timers, staying out for a minimum of 3-4 months at a time, instead of 2-3 weeks at a time with the B.
You're going to probably enjoy the flexibility, mobility, and fuel economy of the class B the most. After that, everything else you discover about them that you like is "gravy", as they say.
Enjoy.
