If anyone is interested in this, I have a guy that I use for shipping big things all the way up to items like watercraft, motorcycles and vehicles. He's got 50'x 8' enclosed trailer, so you item is shipped enclosed, and the load height is about 18" off the ground with a 9' long full width loading ramp/rear door:

Great guy, and he runs OH to Los Angeles, then San Jose and back to OH, about once a month in the summer and once every 6 weeks or so in the winter. He sometimes goes farther east or farther south, depending on what he's hauling.
