I am covering the Blazer in Line-X as well.. If I decide to build bed side covers, it will be out of the material they build boats; marine-grade high-density polyethylene. It can be routered, screwed and glued just like wood (special glue.) Perfect material for the Blazer. Comes in a couple different colors or could be upholstered to match the rest of your interior.
