Advanced RV, a manufacturer of class B units on the 3500 series Mercedes Benz Van is holding their first Open House this coming May 2 - 4 - 1014 in Willoughby, OH. You can go to their web site, to get any registration information. I had the pleasure of driving one of their Ocean One models to the class B B10 Rally in Upper Michigan last May and was truly impressed by their attention to detail in building what I believe is the best manufactured Class B in the market place today. I also was invited to tour their facility and met with the owner and his wife, Mike and Marcia Neundorfer. If you are looking for a unique and elegant class B, you will be excited about this class B.
