It is a 1997 Ford Ranger. Neither wide enough nor long enough to fit 4x8. I bought a ratchet tie down, but not sure how to use it. I took 3 sheets of greenboard today and secured it with twine, but that might not work for 10-20 sheets. The twine probably wasn't even necessary for 3 sheets. I just don't want something bad to happen if I have 10-20 back there.
