Shipping a Boat

I just cut a deal on a '89 v-20 w/ a '90 150 Yamaha out of Charlotte NC. Hours uncertain on the motor but probably less than 200 hrs. Boat is through a good friend's neighbor so I already know the boat from annual trips to NC for Memorial Day weekends

Price is pretty sweet so I can afford the shipping. Except for the trailer it really is a known qty.

It has a trailer but I need to get the boat to RI. Any ideas on shipping the boat and trailer vs. trusting an old trailer that far? Even with a good mechanical checkout I would be a bit concerned that I could have a major mechanical on the trip north and cost myself the shipping fee plus some major hassle!

Recommended haulers? $$?
