2020 Airstream Basecamp X Purchased new in March 2020. Has been towed from showroom to covered parking at my home. Never used, slept in, cooked in, or occupied in any way. Just like on showroom floor. Extras include Solar, Air Conditioning and microwave. Warranty is transferable with Airstream. Includes dolly (see pic) for easy manual moving and torque wrench for lug nuts. For specs go to to   https://www.airstream.com/travel-trailers/basecamp/   
The X stands for off road capabilities in higher clearance, off road tires and rock shields. Dealers are currently sold out and I am told the 2021 models will be at a higher price.
