I pulled a floor out of my second truck to use as a template, it is one sloid sheet of 3/4 plywood. Has anyone used solid lumber in a panel truck before? i'm thinking hickory or goin even cheaper with some treated lumber. I have priced up plywood and all i can het is cabinet grade at 335.00 per sheet, it would take two of them since i have a 1 ton model, any suggestions or thoughts?
