It's a fairly new boat, I'd want to protect it from all the road grime and pebbles myself.
The first thing I can think of is "shrink wrap".... Here on the Gulf coast, I see the boats come in all the time, dressed in shrink wrap. They are on haulers and look like they came a long way. But, the shrink wrap is always intact.
You might look in your phone book, under shipping or shippers. Maybe ask an automotive or yacht dealership.
I would not ride that far without protection. I don't care if I had to buy 5 tarps and duct tape. Pebbles and road grime are not good on your boat.
Trailer: If you don't have bearing buddies, I'd buy them. On the trip, have a grease gun handy and every couple hundred miles or when you stop for gas, feel the hubs to check for a hot bearing. You should do this as soon as you can when you stop, so it doesn't cool off on you. Then, give the bearings a couple squirts of grease. Also, you should give the trailer hitch ball a bit of grease for such a long trip. For just round town, I don't keep mine greased. It's messy. But, for the long haul, the excessive vibration will wear the metal down a little.
Don't forget the trailer spare....!:cheers:
