Thanks, Bill. I see what you mean about the angle iron and being bolted to the tray. It's also interesting how you've attached the turnbuckle to the upright behind the cab, and not to the tie-down bar that runs along the underside of the tray. I'm thinking of doing both... 6 tiedowns altogether... one on each corner attached to the bar under the tray, and another 2 hooked to the uprights. Hopefully, it'll be all trial and no error. :) Thanks again for posting the pics, Bill. Two Couriers and two Freeways... can't be too many of that combination around the traps. Gary
