WOT
Paperwork says it weights 140 lbs. You don't have to take it out as one piece. By pulling pins it comes out as three pieces, which makes it easy enough for one person to handle. Then all you have left is the four pins in the bed which you turn 90 deg. and lift out, leaving the bed totally clear.
There are not any `gears', it is more like a cam plate, located in the middle part of the hitch. It is an amazingly simple, yet totally efficient hitch.
It is a nice experience to purchase a product and discover that it does exactly what it advertised it would do!
Their website has a warning about limitations. It explains that if the king pin is located too far back under the leading edge of the 5er that it still might not clear the cab. If you call the factory with the information on your 5er, they will be able to tell you if it will work in your truck with your choice of 5er.
