This is our second Roadtrek Aventurous RS. We sold our first one then realized we had more places to visit and purchased this one. We have traveled to most states and all Canadian provences, 8 weeks in Alaska (the best).
Roadtrek built their 2012 vehicle on the 2010 Mercedes 3500 base with 6 cylinder Mercedes diesel engine.  The vehicle gets between 15-20 miles per gallon depending on speed and/or mountain climbing. This vehicle has a king/queen size bed (electric couch turns into bed). The Oman generator has 108 hours works great for dry camping. There are 2 cabinets that replace. the second row of seats, one custom cabinet with butcher block top, the other provided by Roadtrek originally. One or both cabinets can be removed and the seats re-installed, the original seats come with the vehicle (one seat has a patch in the top of the seat).
