People need to keep in mind as they read any forum posts you're only seeing a very small representation of whatever the forum community is for. For this and other RV forums if you think about the millions of RVs on the road today and the relatively few forum posts weekly the majority of RV'ers are satisfied with their RVs. The posts you see on RV forums are from folks looking for info, folks who are unhappy with their RV or parts or supplier/dealer or folks who are happy and finally folks like me who like to share their experience with others.
If you consider the fact that RVs are designed to travel thousands of miles on less than perfect roads they are very sound. The key to longevity is good maintenance and care.
That being posted good luck in your search.
