Tom that will be a very nice bed when you are done, no one will want to use it for fear of damaging it

my brother and i debated using something more fancy, we opted for the cheapest pine 2x8s with deck stain since i was always planning to use the truck (hauled gravel last fall with it)
you mentioned finished thickness of 1.25 inch, that's for the planks and you will then trim that down further when installing?
i thought my bed was all 1 inch planks, we only notched where the boards rest on the cross sills and the ends, we left the 2x8s their full thickness under the bed where no one sees anyway
the zinc bolts cost the most in this project, i reused the metal strips, but a few needed material welded in that i took from another truck in the junk pile
perhaps one day i will restore a truck in a much more prefect elegant way and i will need to revisit the proper wood selection.
