Once you've seen the all glass sides in vans like the new Pleasureway Luxor, it's hard to get excited about other kinds of windows (practical or not). I like the all-glass look.
Some vans in Europe have an access door for the cassette and some are an access panel in a bulkhead inside the door opening (if that makes sense). Having the loo open to the great outdoors just seems kinda weird, although it saves the weight and complication of puting a bulkhead there. I wonder if the kitchen side even opens so you could load groceries thru that space?
