Some better pictures and an explanation of how and why...can back up without unhitching. H1946 is correct that only the weight of the front axle is supported...1650 lbs which equals over 2000+ lbs on the rear axle so a tag axle coach with a good frame is needed. It takes aprox 500 lbs off the front axle which with a Dynasty is a good thing.
There are two small wheels that support it when going through a big dip.
When going out West I tow my SUV...more ground clearance when off road.
Have pulled the SUV this way for over 90K miles.
I though I was in the running for the most unusual way to tow a car...
NOT.
