How about this for a bit of luxury?  Not sure I would like to tow it on the road though.

Makabe, Royal Tower is a unique double deck trailer! Wagon equipped with mm. Air conditioning both floors, dishwasher, wine cooler, bar and surround sound. Second-floor lounge is amazing to visit the outdoor terrace where good enough to seduce summer days. What do you think about Royal Tower?  Translated from Finnish
