We had exactly this problem, the trailing arm breaking, on April 26 of this year on our 2008 Cayman XL. Thank God we were off the 65 mph highway, or the consequences could have been severe. We purchased the RV used from LazyDays in Florida. They never notified us that we might have this issue.
After $3700 bill, we are still trying to get some of the money from our insurance company. Probably not happening. Is there anything we can do, or must we swallow the bill? If anyone has any ideas on how we should approach this, would you let us know. We are thoroughly disgusted.
Thanks, Marja Stauffer, Conifer, CO
