Airstream Interstate Ext., Mercedes Benz 3500, 4X4, 5,000 approximate engine mileage, purchase date: January 27, 2023, Vin Number: W1X8ED6Y5NP468734, two extended warranties are available in addition to the asking price. If you’re interested in the extended warranties, I can prorate it from the date of purchase, and the balance will be in addition to the purchase price of the motorhome. The Airstream Interstate GT is fully equipped with all options. It is a EV1 unit for energy usage. The solar panels charges the batteries when it is sitting in the sun light, it also has a second alternator that charges the batteries when driving, and the batteries charge when connected to shore power. This motorhome is rare because it has a 3500 chassis and 4X4, which I ordered and the build time was just over ten months. I’ve had issues with arthritis for several years, but in the last six months it has become extremely painful. I’m having difficulties with stepping up into the motorhome; therefore, I’m selling for the same reason.
