Well, in my experience I had better luck at buying a used one the first time. Our first coach was a 95 Itasca, 34' bought it in late 1997.
Had very little trouble with it. Nothing that would break the bank for repair. Cost was $47,000. cash.
In 2007 bought a 2006, brand new Winnebago Adventurer 36'. Sticker price was $168,000.
We call it our money pit. We have had many things go bad on it and 5 to 6 hundred dollars or more for almost every repair.
I would never buy another brand new one. If I was to list all the things that have had to be repaired on here, They would have to expand the site.
