We have a new 2011 Big Country 3450TS. There are a lot of things we like about our new trailer and some not so much. For instance, there is a little window in the kitchen with a small venetian blind over it. The blind is fixed so that it cannot be raised, just tilted to close out the light. This makes the window very difficult to open. We are wondering was this intentional? If so, what is the purpose of having an openable window if you can't get to it to open?
