I thought they had wood ceilings in airstreams . As for using OVC there should be pvc panels that are flexible. I would probably look for 1/8 “ plywood.

Thanks Patricia, for answering. Do you have a resource? The older ones have a vinyl headliner material with foam on the back, which is glue to the aluminum skin that is attached to the rib of trailer. Most owner that go through this will take away the headliner and scape off the foam and clean which they leave the aluminum exposed. which is a choice of taste. I want to be able to clean and have the material not discolor. Wood is not an option, That would be way too much wood when the cabinets are wood (might sand and leave a light wood color or stain darker, jury still out). The floor will have gray color bamboo and some walls will have a weave color wall paper.

I would look for an FRP Panel, it comes in colors an 1/8" think. They make inside and outside corners as well as divider strips for it.

Thanks, I was looking at that route, I need something that I can work with by myself. 4X8 sheets are hard to manage by yourself, I have to get creative to come up with 2 more hands. But that is something I might end up doing considering my options. Thanks again for the link.
