We have been so pleased with this RV, best one we've ever owned. Engine is perfect, such a dream to drive a Mercedes. Easy to maneuver, park, navigate in traffic, even launch a boat! We are second owners, all systems work perfectly, new windshield, new tires, new battery, comfy Airstream mattress foam topper, loads of convenient storage. Ready for next lucky buyer! MB Engine is 2017, Airstream is 2018.
