I'm a proud owner of a new 2012 FQDS320 - purchased new in July 2011. My family and I love the unit and it's been trouble free for us.
A month or so ago we had a massive wind storm up here in Calgary, AB, Canada. Did $200M damage to the city. I got an email from the operator of the storage facility to come over and check out my unit. Things weren't looking good when I spotted a semi flipped over onto it's side close to the entrance of the storage yard. Anyway, the trailer survived. The wind put lots of stress on the landing gear, but they still appear to operate fine. Just a few days ago I went back to look at my trailer, climbed up on the roof, and noticed what appears to be a missing vent cover right at the back edge of the unit in the middle of the roof. Can you comment on that? Perhaps you can PM and I can email you some images.
