My comment would be to stay away from any "moving company" that doesn't specialize in Airstreams - and that cannot provide a list of satisfied customers. My son-in-law had his trailer (SOB) moved across country via a commercial mover who towed it with a large truck. It arrived on the East coast virtually wrecked (---over $3,500 in repairs!) If the trailer can be moved on it's own running gear I would check with Jackson Center for the name of an Airstream delivery person. Your trip is really a short one - so I would get the best.
