A fitted cover offers privacy and light control when the van is parked. Around a bunk window, the shape and mounting method matter as much as the overall size.
Match the cover to the specific window model or listed vehicle application. Compare storage, coverage and interior clearance, and keep the window's operating and drainage features accessible.
Compare coverage, attachment and storage
Match the cover to the vehicle generation, factory glass or named aftermarket window. A similar overall size does not establish the same shape or mounting method.
Look at gaps around the finished edge as well as the main panel. Compare how the cover packs away, keep it dry in storage and preserve access to window controls.
