5th Airborne Sidewinder pin box changes to design?

[Barbarian Coug]

Purchased a Montana 3150rl ten days ago from Camping World. I ordered a Reese 5th Airborne Sidewinder pin box and all hitch parts at the time of the purchase of the rig. Yesterday I walked into Camping World for an update. The parts counterman stated he had recieved an email from Reese with an update on the Sidewinder. It seems they are making changes to the Sidewinder design and it will not be ready to ship unitl April 4. Anyone have any insight on this redesign and what could be being redesigned?

Well I will answer my own question for the sake of providing information. The Reese Hitch is made in Mexico and they are having "customs issues" in bringing them into the United States. The current date of delivery is now April 27 - they hope.
