Euro slideout

The slide is not new in a B in that Winnebago and Leisure Travel Vans does it with a similar plan on Sprinters. New on a Promaster/Ducato? The really new thing is someone has removed the massive sliding door, done an infill and added a normal swinging door to a B van. That hasn't been done recently with slider door designs. I wonder too with a rear full bath if they didn't also remove the rear doors and build an infill? Forest River MB Cruiser did that with the early Sprinters.
