Depending on the year of your camper, there are some slight changes. Basically, its a big aluminum box with aluminum tube "rafters" running N/S (front/back). The connection points are the fabric and the front/rear lift panels. The lift panels are the only real "structural" connection.
its a 2019.
i guess what i'm really looking for is how it gets layered, say , frame , liner,some type of sealant? , then trim and how all that gets sealed, i believe that is the big problem
