Pretty innovative. More than the 3 beds raise and lower. The rear furniture box cranks up to enlarge the garage. It "comfortably" holds 4, & can accomodate 5 (cot). Standard is a 123hp 2 liter. A 168hp 2 liter is optional. Expensive gas. It heats space & maybe water with gasoline, appears cooking is
propane.
The 3 or 4 lifts are loosely analogous to slide outs [up]. Because they don't protrude to the exterior it might be much tighter than slide units. There are domestic units with beds that raise, but this raises it to a new level. Sure, the pun was intended. Why do people say, pun not intended?
Anyway, if the system works well, it will spread. I think its chances are good.
PS, I guessed, and my guess was wrong. I read about the space heater running off the engine fuel. I was curious about whether there was also
propane on board. I looked at stove pictures and went to Chausson's website. I should have figured that it was a diesel engine, being Europe. But as I recall it said fuel. My Sprinter is diesel, and in Europe the default van fuel is diesel. Of course gasoline is too volatile/combustable. I was politely informed these are diesel units. Tip of the hat to Brian.
