If you are going to carry SH in your truck you will need to rhino line more than the bed. Do not underestimate the corrosiveness of the fumes... You better think about the under side of the truck too.
Marcus is right about the fumes. The entire underside of my truck and the inside panels all are rusted, just from SH being present! Rhino lining would probably help the bed itself though?
