Somebody mentioned this point above already. But it's very valid. Probably nobody has owned recent models from enough of the manufacturers & done an in depth comparison (like Consumer Reports does for cars). So, that said, people tend to be overly positive to what they own (unless they have a real piece so to speak).
But here's my thoughts regardless...
Born Free & Lazy Daze would be among the "best". Nexus seems very strong also. Never owned any of these manufacturers. But I've read enough about them to appreciate the quality that goes into their construction.
Then there are all the volume builders.
Here's my personal opinion from our shopping (&, in the spirit of full disclosure, we got a Forest River Sunseeker):
Winnebago: We felt they were over-rated. Many happy owners no doubt. But older style construction materials. Fiberglass roof is great. But uses wood walls. That technology is older. Problem is wood walls can absorb moisture &, if / when that happens, it will lead to delam which is one of the biggest drains on RV values. Higher price based on name.
Forest River Sunnseeker: Also fiberglass roof. But Azdel walls (for those that don't know, Azdel doesn't absorb moisture so delam won't happen, has a higher R value, & is lighter). So 2 check marks. As I scanned through the list on the 1st page, our unit has the vast majority of the items. It does not have carpeted storage but we'd rather it not be carpeted given that we store dirty stuff in them. But then again it has some things the Winnebago doesn't such as a bigger gray tank (39 gallons). Pretty good reputation among at least newer owners (which I would agree with as one of them). I think older Sunnseekers left a lot to be desired. But since Warren Buffet bought out Forest River, he really sank a lot of money into improving the Sunseeker line. Value priced.
Several folks said this point above too. But it's spot on. You could take the "best" class C manufacturer & get an absolute lemon for a variety of factors. Likewise, you could take the "worst" class C manufacturer & get an absolutely perfect unit.
Good luck on your search!
