Excellent video Joe! It’s amazing that it only took slightly more than a one gallon jug to winterize This Airstream Class B motor coach. Nothing freezes at my house in Califonia, so I’ve never seen this done before. I like the four seasons coaches, but just like in your own home, if the heating fails, a lot of damage will happen.
David, the Interstate Nineteen started production in the 2018 model year. Your model may be a Interstate Convertible Lounge. There are some support articles for older coaches on support.airstream.com
