LAarchitect, I used SHowroom transprot last year to get my Safari from NJ to Tx. Very reasonable and great company to work with.
My brother used a trucking broker to get a boat from Maine to Louisiana. You can try that route. The company posts the job on their network or whatever and then truckers can pick and choose the work they want. I assume like Showroom Transport as well. My brothers driver was driving to Tx from Maine for family and since he had to go anyway he made a little $ and attended his family function. The rate my brother got was unbvelievable.
