A trailer powered by electric motors can be used in conjunction with your vehicle.
A trailer attached to a vehicle can be the best way to go camping under the stars and all the comforts of home for those who love to travel the roads. A fully-sized motorhome is a great option for some, but a trailer towed option works well for others who are looking for a quick getaway with limited options and a lot of cost. It’s not surprising that trailer-towed motorhomes have a lower fuel economy and significantly less aerodynamic performance than their fully-mobile counterparts. Airstream is a well-known name in the camperhome industry.
It would be necessary for the vehicle to communicate with the trailer in order for it to calculate the power required for forward motion. There isn’t currently an interface to do this, other than the connector that powers indicators and brake lights. Airstream envisions a fully autonomous camper that can drive itself to any destination. Airstream has an autonomous vehicle that powers itself. You go to sleep at night, and when you wake up, you are at Yosemite. This vision is far away, but it is possible.
