Yes, I have a sawmill and ten acres of trees, but didn't have anything already cut and seasoned that would work. I want to take this truck to a vintage tractor and gas engine event in August. No relief cuts and I have never seen them on original wood. My'59 has original bed wood and so does my recently aquired '29 model AA. The strips do what's necessary to keep it flat enough.
