Mike, I'm on my 3rd Winnebago, I currently own a 2004 35-U which, I've had extremely good luck with. The Winnebago years that you picked out are very solid years and I wouldn't hesitate buying one! Winnebago DP RV's from 2004 to 2008 have good craftsmanship combined with a CAT engine and Allison transmission are hard to beat for reliability. What I've been reading and hearing about newer Winnebagos if I was buying new I would choose to buy a Newmar and your hearing that from a Winnebago guy. JMHO, Good Luck with your new coach whatever you decide to buy!
