Well, hopefully the saga with the bent brackets has finally come to an end. FR agreed to cover the warranty work and I brought it to the dealer (Travel-Mor, Ottawa, Ontario, Canada), last week. The repair was awesome, (I'll forward pics in the near future) and they told me that the factory brackets were toast. They re-engineered the bracket set-up using beefier angle iron and a slightly different configuration. Also tried, as best they could, to adjust the vent line. Also told me that the repair time was longer than they had been allocated, however they persevered and did a quality repair. They did caution to fill the tank as slow as could be in future, but I believe that their fix will certainly do the trick.
Everyone that has a 2109s should have a look at these brackets(!).
