Hello and welcome to the forum.
We have owned our 06 280C since 2007 and have enjoyed it as I'm sure you will. I did notice one thing in your pictures that I wanted to bring to your attention. There is a strap on the hinged cover over the tip out that should always be attached with the clamp. It is there to hold the cover down incase a wind gust should try to ripe the cover off, or at least bend the hinge back. Of course, you need to disconnect it before bringing the tip out in.
Good Luck camping and enjoy all there is to see.
