When looking at class "C"s, they take a pretty big depreciation hit, almost in the range of 20% when you drive it off the dealer lot.
"B"s, when looking at a 2012 used model versus a 2013-2014, there might be $4000-$5000 difference at most. With the market as it is now, might as well keep one's eyes peeled on rvtrader, and be prepared to buy within minutes to hours of seeing the listing.
A good example of this was a PW Excel on PPL's site I saw today that went for a price between $75k and $79k. It never made it to the webpage before it had a "Sold" tag. (I check PPL daily.)
