I myself would show up an hour early. Hopefully get loaded with plenty of time to get to the delivery. Get a 10 hr break and be available to reload when empty. The other choice, if they take all day to load, would be to start out with a fresh 14, having taken a 10 at the Shipper. Then deliver an hour early, hopefully still have enough time to reload, then take another 10. This is when communication with dispatch is important. Knowing what they have planned ( if anything) for you next. Either way, communicate with them, let them decide to push the delivery out, if needed to finish a 10 hr. break. Showing up early should give you plenty of time either way. I wouldn’t push the delivery out until it necessary. Why risk losing a day, especially after a short trip. The goal is being available to run.
How far away will you be from your shipper? Will you have a 10 before heading there? If 1 hr or under from shipper start your clock at 1600. you will be able to get to receiver within the 14
But never make it out in 14. Can't do a 10 between pick up and delivery, and can't do pick up and delivery within the 14 hour clock. Even a split won't do it. So the only option is possibly stay at the receiver after delivery for a 10. All sorts of problems with that, especially if you need a bathroom, or if the customer doesn't allow you to park there. When will people learn to turn these impossible loads down? When will it not be our job to do this kind of thing in their time frame and simply do it in our time frame? They can ALWAYS schedule things more favorably for the driver! !!! A little earlier pick up, a little later delivery. No big deal.
DO NOT do a split break unless you do them often and have ZERO confusion about what makes them legal and what are the common mistakes when doing a split break. A split break is not something you just figure out when your schedule is much tighter than usual. It is very easy to screw it up by just a few minutes and turn that into an egregious HOS violation and have to take a surprise 10 hour break. You need the shipper to cooperate with whatever your plan is, not just hope the shipper will put you first in line to get loaded when you show up. Find out the time the shipper plans to load you and then make your plan.
Do the p/u, drive the miles, stop your clock by going off-duty or sleeper for at least two hours(assuming you haven't stopped your clock once already), make the delivery then do a minimum 7-hour sleeper break(depending on how long you sat before delivery). It screws up your day a bit but, depending on how fast they unload you, you could be rolling again by afternoon.
