Recently I purchased a 2004 Airstream Land Yacht from Colonial Airstream in Lakewood NJ. The price was right and the unit was clean and well prepped. Away I went and just before crossing the Chesapeake Bay Bridge the auto brake crapped out. Had Good Sam road service disconnect the hand brake mechanically and drove on home to South Carolina where I had my local shop repair by installing new pressure switch's. I want you all to know that when Colonial Airstream understood the problem, they took care of it. They stood behind their product even though it was a used unit. Thank you Colonial for helping me with my problem!
