Galley hinge on a Yodet Toter and awning rails

Hi there...does anyone know what kind of hinge is on the 2006 Yoder Toter 5x10? Its leaking in the rain. Having it resealed. Wondering if we can get an awning rail put in at the same time, and if so what size. I am trying to do some hmwk on this before the work begins but don't know where to start... Thanks for any suggestions.
