Welcome to the forum Stu.
Current Class B manufacturers are listed here:
Try and see a few more and test drive them. You certainly have lots of choices now.
The first Class B that caught my eye was a Roadtrek. I ended up buying a Roadtrek. My budget only allowed for a used van.
I've been thinking about running a poll on the forum. Something like Class B Forum members picks. We can break down Class B RVs into categories.
1. Pop tops like GTRV Westy, Safari Condo and Pleasure-Way Traverse.
2. Gas powered Full sized normal width vans with high roofs like the Roadtrek 190 series, Pleasure-Way Lexor, Safari Condo (hard top), Sportsmobile and Great West.
3. Gas powered Full sized wide vans with high roofs like the Roadtrek 210 series, Pleasure-Way Excel and Great West Classic Supreme with a slide-out.
4. Diesel powered Dodge Sprinter based models from Roadtrek, Pleasure-Way, Great West Van, Gulf Stream Coach, Leisure Travel, Airstream, Xplorer Motor Homes and GTRV
Sportsmobile builds custom vans so they fit in almost all the categories noted above.
Right away you can start to eliminate some based on vehicle type preferences.
If you're going to be putting on a lot of miles you probably should consider a Class B RV based on a Dodge (Mercedes) Sprinter. Maybe 22 mpg for the Sprinter vs 14 mpg for gas powered Class B's. Sprinters cost more though.
I like Sprinters and would have a tough time choosing between them. I just quickly looked at a local dealers online inventory and once again confirmed that Sprinters are out of my reach.
I also like the space in the wide body vans but, I prefer a normal width van because I drive on a lot of narrow roads.
The wider B's and Sprinter B's have enclosed bathrooms.
