The main issue I have with it is the tongue weight goes from 20 pounds with a conventional 4-wheel-down method, to multiple thousands of pounds. That will throw any class-C into an over weight condition. I also would be very concerned making a sharp turn in the forward direction, It seems the tow vehicle is too close to the motor home. My Jeep Liberty is much farther from my PC's rear bumper than that thing, but when in a very sharp u-turn scenerio, the two vehicles get within inches of eachother.
Very interesting. Thanks for sharing Billy.
