The 2016 Nexus 27V Viper Class B I just checked out seemed to be base-priced quite fairly for a Class B .... which can sometimes be outlandishly high priced. Of course to really set it up nicely many options from it's extensive list should be chosen .... thus quickly raising it's price into the stratosphere.
The 27V's black tank and propane tank capacities are a bit small. It's furnace capacity is generous. It's air conditioner capacity is a bit small. It's built on the great Ford E450 V10 chassis for overall ruggedness, reliability, ease of getting fuel everywhere (unlike diesel fuel), and ease of getting service everywhere (unlike some of the off-shore chassis making their way into the U.S. market). It appears to come only with slides (which some folks don't care for).
Happy hunting .... and be sure to always look "under the hood" of each motorhome candidate well beyond just floor plans and layout. I always look at specifications FIRST, and then look at the more obvious and visible things. Even crawl under candidates, if you are able, to see how well the coach manufacturer did things where the user can't see it -> for instance you want bundled secured wiring everywhere, high-mounted enclosed plumbing, and a high-mounted built-in generator fueled by the same fuel as the main engine.
