Sale Pending. 2018 Airstream Interstate 4x4. 2 extra house batteries, Victron solar controller, new Michelins, switch for Fusion gps. “Karenvan”  just finished her primary mission to visit 40 national parks. She did 14,000 trouble free miles over 7 weeks time. Her small size and 4x4 wheel drive allowed her to go where other rv’s could not. She climbed over the Rocky Mountains, sunned herself on the beaches of Florida, and traveled below sea level in Death Valley. She was the perfect vehicle for this. We were able to stay inside most of the parks with no prior reservations ( even the Grand Canyon)  She has averaged 16.7 mpg over the 42000 miles. A new Interstate's list price is over 200000$.  We are selling due to health issues (parents). Have title in hand.
