Moin together, with my camper (Knaus Traveller C500 from 2001) the alcove window is defective. Built-in was a frameless Polyplastic Roxite with cut-out about 70x40cm and aluminium rails directly attached to the window Due to the lack of availability (and also the prices) I would like to evade the used market and look for suitable windows. The question: Which windows can I install here? Would a Dometic Seitz window also fit? On the vehicle also use directly with the windows or are they incompatible? In theory everything that is larger than the cut-out would have to fit on windows, correct? Can the stands compensate for much lateral difference? Could they be moved in retrospect? Are there any sources where I can find scrappers/repairers who may slaughter this model or similar (seems to be a quite common model)? Thank you for any help!
