There are so many RV ideas that they have, that I wish would hit this side of the pond. What I've seen, one of the newest "must have" features in US rigs this year is adding speakers and televisions... blah.
At least we are seeing SMEV flush stovetops and sinks, although I'd like to see more rigs use the combined stove/sink for additional space savings, like pictured above. That, and more electrical appliances, so there are fewer "giveaway" ports on the outside of the rig.
One of the nice thing about "B"s is the stealth aspect. Where someone might have to slow down and maybe look closely to see if the van is just a passenger van versus a motorhome, a class C is a giveaway...
