Being a boater with more confidence in marine situations you might want to go to youtube and watch the videos from the Sailright company. They do show installing methods in the video for "rat fur" types of overhead and sidewall lining materials in sailboats. Here is a link to their youtube channel.
Marine methods, auto installation methods, van conversions, travel trailers, they all use this type of product although of course it is not the only type of material that gets used for these applications.
has a lot of useful videos for renovating travel trailers such as how to install headliners and how to sew your own upholstery for cushions or how to make a protective cover. They also sell useful products. I just ordered some awning
track and Keder rope insert from them as I wanted it in the color black and they offer that color.
