Oh I know OD isn't trying to screw me. I just had always been told 4 drops and 4 hooks, just hadn't heard it explained the way you did is all. OD pays me well so I'm a happy camper.you can add has many has you want.I just alway's explain everything I do in the comment section.If they pay me or not.Never had a problem.The 5 hook's is if you have dropped trailer and a Supervisor ask you to put the trailer or trailer's to the door.Then you have to go back and rehook.You then have to add the hook and drop to your next trip.Just explain what you do.OD is not trying to screw over on no one.You have to look after yourself on this.
