As I'm still in the research phase, but I plan to purchase in late '15, I just read the 2014 "Motorhome Comparison Guide" by Randall Eaton. From 2006-2007 and 2010-2014, Foretravel took the top spot.
From 2006-2014, generally speaking, these manufacturers rated as follows: Country Coach 2nd - 2006-2007; and 1st 2008-2009; Tiffin 3rd; Newmar 4th; American Coach 5th; and, Entegra 6th. Their "rating chart," rated DPs on four general areas: Construction; Customer Satisfaction; Dealer Rating; and, Resale Value. They did not rate Newell or Prevost.
It's good to see Foretravel at the head of the class, but it was curious that in 2008-2009, Foretravel dropped to 3rd overall and Country Coach was rated #1.
