Charles,
They will trailer it behind their truck more than likely. Providing the ball is a good idea. You can arrange a flatbed but it will likely cost more. Both mine were just trailed as normal. Don't forget to consider putting new tires on prior to the trip. They will fail on a cross-USA drive if they've been sitting more than a season or two.

They will literally drop the trailer off in front of your house. It's very convenient.
