I bought a 2006 Essex with 18,000 miles on it in 2009 for a song. I'd like to upgrade but I just can't take a hit for a new one. Good used one's are getting hard to find. Only bad thing with an Essex older than a 2011 is the E-Plex computer. It's obsolete but Newmar still carries spares. Only thing is an E-Plex tank monitor went from being $97 in 2010 to $1200 now. 2007 on up have the comfort drive and single windshield. I paid $209 for mine back in '09 and can probably still get 80% of that now if I sold it. I'm looking at a new 2014 for $500 even, but in 2015 they went to a K3 chassis and ISX 600HP.
