A new company called Aboard has just launched its first product, the T4, at an event in Denver, and it is the most feature-dense electric travel trailer announced since the Pebble Flow. The T4, short for Trailer for Four, combines a 41 kWh automotive-grade LFP battery with a 40 kW electric motor on the rear axle, a silent onboard generator capable of 60 kW, and a 1.2 kW solar array on the roof. Combined power capacity tops out at 200 kWh. The dry weight sits around 6,500 lb with a 7,500 lb GVWR, which puts it in reach of most midsize EVs including the Rivian, the Cybertruck, and the Model Y. Aboard's stated goal was to make RV ownership approachable for first-timers, and just about every technical decision in the T4 traces back to that idea.
The electric travel trailer space is still early, but it is getting crowded fast. The Lightship L1 has been in deliveries since late 2024, the Pebble Flow is in production review stages, and Evottex has also entered the conversation. What separates the Aboard T4 on paper is the depth of automation it is targeting at launch. The app-controlled self-parking system uses 360-degree cameras and onboard sensors to back the trailer into a site autonomously after unhitching. Coupled with the powered, auto-leveling corner jacks, the pitch is that getting set up after a late arrival in a tight campsite can happen without shouting instructions or guessing on blocks. Aboard also includes a powered clamshell rear deck, a motorized awning, two side entry doors, an exterior shower accessible directly from outside, outdoor power outlets including 120 V and 240 V, and a Starlink port built into the electrical panel. The dual-door layout specifically addresses off-grid use: when you own a parcel of land rather than a numbered campsite, having a direct entry to the bathroom from one side makes practical sense.
Inside, the T4 runs on what founder Tao describes as a full automotive electrical architecture, meaning a centralized vehicle controller manages the battery, motor, jacks, doors, and all powered accessories through a single integrated system rather than discrete RV-style converters and relays. The interior features a dinette with 270 degrees of glass that converts to a queen bed, a kitchen with a 3,500 W induction cooktop and a fridge-freezer, a bathroom with an overhead rain shower and a skylight, and a rear lounge area with an L-shaped couch that also converts to a queen bed. The clamshell deck is rated to support two adults. A full speaker system and soundbar run throughout. Water capacity is 53 gallons fresh, 35 gray, and 34 black, which Aboard says supports three days of comfortable off-grid use. All body panels and doors are aluminum construction on a steel chassis, with automotive-spec weatherseals and latching hardware throughout.
Bottom line: Aboard is making ambitious claims for a company that has not yet shipped a single unit, and real-world towing numbers, durability data, and production timelines remain unconfirmed. But the T4's combination of self-parking, a hybrid power system, and automotive-grade construction targets the exact friction points that keep first-time buyers away from travel trailers. If Aboard can deliver a pre-production unit that matches what was shown at launch, this becomes one of the most compelling electric trailer options on the market. The company to watch is whoever actually ships first and gets independent reviewers behind the wheel.
