A typical RV has to plug in at a campground to run the power inside. But Airstreams newest Basecamp 20Xe trailer is designed to power itself in remote locations: If you want to spend a week in the wilderness, you can theoretically use an induction stove, keep your laptop charged, turn on the air-conditioning, and have hot water for the showereven if youre nowhere near any utilities.[Photo: Airstream]Over the past several years, weve seen a growing demand from our customers for what we call energy independence, says Bob Wheeler, Airstream president and CEO. The flexibility to not have to go to a campground with established power and energy supplies, to give them the freedom to camp anywhere they want. The phenomenon was really exposed during the pandemica significant shortage of campground and campsite availability.A different electric Airstream model, the Trade Wind, has a smaller battery and works well for a weekend of use, but the company got feedback from customers who wanted to be able to stay off-grid longer. The new Basecamp has four times more power, with a 10.3-kilowatt lithium battery, 600 watts of rooftop solar, and the option to plug in an additional portable 300-watt solar panel if youre parked under a tree and want to stretch the attachment into the sun. (The Basecamp will start at $76,900.) The flat solar panels on the roof, custom-made for Airstream, are also designed to work efficiently even in partial shade.[Photo: Airstream]All the plugs inside run directly off the battery, including the optional AC (in a small size, so it runs efficiently) and microwave. The heat and hot water also use the battery, though if someone wants to camp in cold winter weather, they might want to add an optional propane tank.How long the power lasts depends, of course, on how much power someone uses and how sunny it is outside. But theoretically, if youre using those larger capacities very infrequently, you could be out there indefinitely, says Bryan Melton, vice president at Airstream. The bigger limiting factor is access to water, though the trailer is designed to use water efficiently. The shower recirculates water until its heated up, and the unit also has an option for a composting toilet. [Photo: Airstream]One thing the battery cant do: help the vehicle in front of it tow the trailer when it moves (which would save gas, or conserve battery power if an EV is doing the towing). Although the company released a conceptual design in 2022 for a solar-and-battery-powered trailer that could propel itself, that version isnt there yet. Its likely to come later. Were watching for the right opportunity to do something that has at least some of those features, Wheeler says. Lightship, a startup competitor with a luxury electric travel trailer, does offer that option.
