Emergency airstream rv service in chattanooga ????

If this is a warranty issue, then a call to Airstream will give you guidance. Otherwise, unless it is body work or axle replacement, any RV technician could do the work with, most likely, off the shelf parts.

Not a recommendation, but there used to be a Camping World store and service on the south side of Chattanooga going toward Atlanta. Back before Marcus took over, they were a good pick. Now, haven't been there in may years.

Your nearest dealers are Huntsville, Atlanta, and Louisville, TN.

Don't know him, but here's a page for a local master certified RV tech. A quick glance at his page gives me the impression he knows his stuff, bet he speaks "Airstream".
G&G Mobile RV Repair

Edit: found the web page.

Give him a call, see if Airstream will use him if under warranty.

Good Luck!

I'm not familiar with the area. Maybe you can call some campgrounds and ask about local mobile RV techs their campers have used?

Hopefully someone has a better response.
