You will find information like span tables on lumber like this when
standing on end, as it is used in construction. I have not seen
anything addressing strength in the other direction. I have found
that boards like this bend too much for practical use before they
actually break. You know, you can actually buy ramps for this
purpose. Here's an
example:

They will be light, strong and they'll come with a load rating. They
should also last a lot longer than lumber, especially if it sees any
weather out there in the truck bed.
