The Lightship AE.1 Camping Trailer is poised to revolutionize the challenges associated with EV towing and the general drag imposed by conventional trailers. While electric trucks offer instantaneous torque that makes trailering effortless, their battery range often diminishes significantly when towing. Lightship, an emerging travel trailer company, has engineered a dual-pronged approach to mitigate these issues, aiming to create a trailer that is nearly “range neutral,” benefiting both electric and traditional gas- or diesel-powered tow vehicles.

A fundamental innovation of the Lightship AE.1 is its self-contained electric propulsion system, which includes an electric motor and a robust 77-kWh battery. This onboard power source substantially lessens the burden on the tow vehicle, with Lightship estimating it can recover approximately half of the range typically lost during towing. The system also incorporates regenerative braking, which assists in deceleration and partially recharges the battery. Additionally, a solar panel array on the roof provides up to 1.8 kW of supplementary power, enhancing the trailer's energy independence. Lightship anticipates this battery setup can support 300 miles of typical towing before relying entirely on the tow vehicle. To ensure seamless compatibility with any tow vehicle without modifications, Lightship developed a sophisticated force sensor on the trailer yolk. This sensor performs 10 readings per second, detecting whether the trailer is exerting a drag or a push on the tow vehicle. The electric motor then modulates its output to maintain minimal force in either direction, ensuring the tow vehicle is only lightly engaged in accelerating or decelerating the trailer. This innovative design not only benefits electric trucks and SUVs by extending their range but also improves the fuel economy of gas- and diesel-powered vehicles by reducing the workload on their engines.

The second critical aspect of the Lightship AE.1's design is its focus on aerodynamics, which typically accounts for the largest reduction in fuel economy or battery life when towing. Lightship’s groundbreaking solution is a telescoping roof that allows the trailer to physically reduce its height while in transit. The trailer is ingeniously constructed in two distinct sections: an upper half that fits over a slightly larger lower half. Four electric actuators facilitate the lowering of the top section, effectively reducing the trailer’s overall height by more than half. This dramatically shrinks the frontal area exposed to the wind, leading to a substantial reduction in aerodynamic drag. Lightship estimates that this shape-shifting design, coupled with meticulous shaping of the trailer body, helps recover the remaining half of the range lost to towing.

Beyond its remarkable range-extending capabilities, the Lightship AE.1 offers a distinctive user experience. Upon reaching a campsite, the roof can be raised to provide generous interior space, comparable to similarly sized conventional trailers. A notable feature is the inclusion of significantly more windows than typically found in other trailers, offering expansive, panoramic views. Due to the telescoping design, conventional upper cabinets are not feasible, prompting Lightship to integrate large windows in their place. Furthermore, the company custom-engineered its own HVAC system, discreetly tucking it under cabinets and distributing heated or chilled air through hidden ducts, thereby avoiding any roof-mounted units that would compromise its aerodynamic efficiency. Lightship estimates that approximately 80 percent of the trailer’s components were custom-engineered and manufactured by automotive suppliers, rather than relying on traditional RV parts. Ben Parker, co-founder and chief technology officer, remarked that the engineering effort was akin to designing “an entire EV except for crash testing and a steering wheel.” Unlike its competitor, the Pebble Flow, which can self-drive around a campsite, the Lightship, being a tandem axle trailer, faces complexities with tire scrub on its unpowered pusher axle during maneuvering, although a solution is currently under development.

Lightship is adopting a strategic business model, commencing with the launch of its flagship models to fund the development of more affordable options. The company recently delivered its inaugural production trailer, with all Cosmo Founders Series models already sold out. Subsequently, Lightship will introduce the AE.1 series, featuring the Atmos model priced at $184,000, which, when fully equipped, weighs approximately 8,200 pounds. Customers can also opt for the Panos model, priced at $151,000, which includes a smaller 44 kWh battery, reducing the trailer’s weight by 500 pounds.
