Interesting German camper concept

Yes, interesting. A "powered" travel trailer... they are claiming you could safely tow a larger TT with a small vehicle, because the "felt" weight you are towing is reduced dramatically. Sounds iffy... what happens when the TT's battery dies during the trip? Suddenly you have a dangerously overloaded tow setup. "Tail wagging" could take on a whole new meaning when the tail has its' own power!

The idea of being able to move the TT AFTER it is disconnected seems like a great idea.
