There is not that much difference in the Mercedes Benz Chassis of 2010 to 2013 to worry about. The 2014 chassis was redesigned cosmetically in the front end and had some desirable safety features added if Pleasure-way included them. The front end redesign was to unify the look more with its high end luxury cars. It was subtle. The steering wheel was redesigned as well but the rest of the cab not much different. All in all go with the price.
