there was a campground adjacent to my hotel in France. jam packed with TTs about 22 ft long with many/most having a fitted screened room similar to a R Pod, the ones I could see in the front door appeared to have a U shaped dinette that could be made into a bed. nothing fancy but serviceable.
saw one large class a at an airport, frankfort IIRC everything else were TTs and class Cs.
stopped at a dealer and wasn't impressed.
my friend had a C and I was impressed with the cabinetry that appeared to be formica, not US fake wood vinyl shelf paper.
had the windows that were plastic, hinged at the top, with shades/screens depending on which way you pulled them.
