Mine is varnished. I wouldn't want to add the weight of a sheet of stainless steel. Bedliner is a horrible idea, impossible to clean.
If I did stainless, it would be a very thin sheet, so weight wouldn't be an issue, but it is fairly expensive. I agree on the bedliner, and didn't mean to imply it was a consideration. Varnish is certainly the least expensive option.
I think I may go another route though - a 16x32 cutting board in (the exact dimensions needed). Cons are the expense, same as a stainless sheet ($30ish), but it would be easy to clean, durable to cut on for food prep, and easy to maintain.
