You'll get charged for the extra overhang.
 Last pin I shipped with Ego I put in the correct dimensions and then got stung extra as they had calculated it differently and then I got stung again for over $100 for the driver to have to help unload. This is after I had ticked that driver would have to help. The pin was a woodrail and so the pallet was much lighter than a normal pin. Just to add though that all charges were taken direct from my credit card ( typed in at payment) and some weeks after delivery.
I wont be using Ego again.
