au_ee, did you ever find someone in North Alabama to help you?
FWIW, I either do repairs/maintenance myself, or I drive to Alachua, Florida. Friends of mine used a central alabama area rv repair company to change their Fantastic fan ... well, they ended up with a massive dent in their roof. Another friend used Dandy to diagnose and repair a leak ... $10,000 dollars later, he found PROPER and knowledgable repair in Alachua, Florida. I hope you found someone close to you, but be careful about what you allow non Airstream experts do.
BTW, I heard Sonny in Montevallo is truly an expert. Unfortunately, he's mostly a one man crew and keeps a long waiting list.
