Is there a durable wood floor?

[68shortwide]

The wood bed floor in my stepper is just absolutely obliterated so I’m looking at options for replacement. I’m already planning on new hardware and rails but plank material is where I’m stuck wondering what path to take. It’s just a half ton so it won’t see obscenely heavy cargo weight but I would definitely like to use it for moving engines/engine and trans combos. Would something like Oak hold up to a bbc on a rolling cradle? Searched around and besides Oak, Teak, and pine I’m kinda striking out on ideas.
