When we were thinking of selling our current Airstream Interstate class B van so we could get into a new one, we had narrowed our choices down to the Coachmen Beyond Li3 AWD, or the Pleasureway OnTour 2.2. The units from MAD / American Patriot are gorgeous inside, but there are a few small things about them we weren't crazy about, so they didn't make our short list.
In the end, we weren't able to sell our existing unit for a price we liked which would mean we'd have to put a lot more money into a new unit than we wanted. So, we decided to keep our existing van and make a bunch of upgrades such that it has most of what we wanted in a new unit anyway, and at a far lower cost.
Actually, that previous paragraph should give you some hope for better prices on the used market in case you're considering a gently used Class B vs. a new one. If you're not, you should probably at least take a look at that possibility.
