Tie down for transport? Pull me out of a sandy wash? Pull KOV out of the snow? It is true the Gasser cannot be flat towed with all four wheels on the ground but the diesel can be and remember this van is diesel only where the parts are manufactured in Italy and is manual or automated manual there too. No Automatic. This attachment will not work for flat towing anyway as a frame bracket would need to be installed behind the bumper and across the vehicle not simply a single tow eye on one side. I think all cars now have just this sort of removable tow eye, at least all mine do.
Also used to winch a disabled vehicle up onto a roll-back truck.
Several years ago I had an accident in a Sprinter resulting in the vehicle ending up straddling a rail of a railroad track paralleling the highway. Two tow trucks -- one lifting by the trailer hitch, the other by the front bumper eye bolt -- were able to take most of the vehicle weight (loaded about 11,000#) and ease it over the rail and off the tracks. At least on the Sprinter the front fitting is very strong.
I don't believe that the eye bolts are used in any way during production or shipping to dealers. Everything is regulated these days and I would guess that these front "towing" points must meet some Federal regulations. Anyone want to research this?
