Actually, looking at the truck, I don't see how the stake-hole mount would work. On the Tacoma the top of the bed sides is covered by a thick layer of black composite material, like that which lines the bed. There are no stake holes visible anywhere. I'll communicate with the Breedlove company before I go further.
This is from an 06 which I believe is similar:
That black composite material comes off, there's a plastic latchey thing, and the rest snaps off.
However the post or stake holes are there but pretty useless.
