I put this truck together out a pile of parts. It looks decent but will never win a car show. Not a daily but use for my sideline sawmill duties. This was my plan all along.
The wood floor beds are awesome. In my opinion, I would use a hardwood like white Oak. I've owned a few and the hardwood held up fine. Had an old Ford step side with a pine floor and it rotted rather quickly. Use boiled linseed oil to help preserve.
