California startup Aboard has released specifications for its autonomous T4 travel trailer, which uses electric motors to assist the tow vehicle and can park itself. The 7.2 m, 2.95 t trailer features solar panels, a 41 kWh battery and a 60 kW generator, providing up to 7 days of off-grid living. It includes an induction cooktop, climate control with a heat pump, and a separate bathroom entrance. Series production is scheduled for late 2026, with a base price of $80,000.
