Essentially new, never used. Significant upgrades include: 300W solar package with lithium batteries. Twin air conditioners with heat pump and furnace. NanoCoat exterior finish. On demand hot water. Upgraded Microwave convection oven. Blue Ox sway bar/weight distribution system. Remote backup camera. Still covered under transferable factory warranty. This beauty is fresh out of its 90 day factory reset to check and fix functionality on all systems. Is currently winterized. A quality Airstream through and through!
