I posted this in another topic but it was old and had 58 posts so I'll make a new I work pre-load and run air. M-F Clocked out at 21hr preload and about 2 1/2 air. I was asked to run air tomorow ... Going to the airport sorting. Loading the truck up and bring it back to the hub for Monday and then deliver sat air. Is this all OT for me ? "This is called the pre-LOAD not the pre-STACK"
