Here's another thought....
I rarely read posts on car or truck forums but I read several different RV Forums daily. If you are like me you will read lots of RV Forum posts about tire and suspension problems. But I always keep in mind the majority of RV owners aren't reading or posting on RV Forums. People visiting or posting on forums are usually there for a few reasons... looking for help with a problem, need to post regarding some issue, like to offer help (like me) or curious about RVs and RV lifestyle.
On the RV Forums we are seeing just a small sample of RV Owners so it may look like there are a lot of problems but in reality the majority of RV owners aren't having problems.
If I read car and truck forums as much as I do RV forums, would I read about a lot more tire and suspension problems on those forums.
