Greeting all, I wanted to let everyone know that the porthole window was repaired by the dealer who sold us our trailer. Originally the factory did not want to cover the window under warranty. I am not exactly sure of what took place next but finally the dealer got permission to replace it without cost to us. The end result is a new window that was installed very well and it looks like original condition. They entire process took 3 weeks. I am glad it wasn't in the prime camping season. Thanks for all the help everyone has given us on the forum. It made this easier and helped us work through it. I hope I can return the favour soon.
