Self-propelled trailer technology looked quite cool and cutting-edge on the curvy Dethleffs Coco, and it looks even cooler below a classic Silver Bullet silhouette. The Vision Vehicle isn't the only fun electric toy Thor Industries has brought out at the Florida RV SuperShow. The new Airstream eStream concept packs an e-drive that can propel the trailer's weight, maneuver into tight spaces via remote control, power up appliances at camp, and even serve as a backup power supply at home.

"Self-driving" and "self-parking" are not concepts we originally thought about for towables, but three and a half years ago, Dethleffs opened the door on that possibility when it partnered with ZF on the E.Home Coco trailer, a dual-motor caravan concept that promised to greatly decrease the pull on the tow vehicle, boosting efficiency and range.
