I don't know anything about their service department but Sanders RV in Alachua is an Airstream dealer and I have been very satisfied buying parts from them. They apparently have quite a lot of stock. I needed the three dimensional "Safari" letters for my trailer. They initially said they were no longer available but called me back and told me they had gone through all their old decals and found a set. It appears to be a small family run business. I have also seen good recommendations on here about their sales department.
