We looked and drove a 2010 4333 and really loved the Comfort Drive. However we did not like several things about it that turned us off. First, it only had the ISC engine and in my opinion, was under powered. Secondly, if you open any of the overhead cabinets on the passenger side, you'll find about 50% of the interior of the cabinet is taken up with some sort of ducting that is boxed in. Thirdly, the tv placement were not to our liking at all. There were some other minor things, but really insignificant.
Newmar makes an excellent quality coach, we just couldn't find the one that we felt met all our needs. If this one is to your liking...I don't think you can go wrong with it.
