We've used this receiver hitch crane for at least 15 years. I've loaded countless deer, elk, antelope and even a moose with it. We usually hunt in snowy conditions so it's easier to drag an animal close to the truck. We also do a lot of ranch hunting so even if you have to walk several miles to find the game it's possible to return later with a truck.
The whole crane breaks down into component pieces for transport. It originally came with cable loops, but my BIL (who is an excellent metalworker) replaced those with pulleys and added a circular Teflon collar at the base for ease of rotation.
That's my son with a 300 lb whitetail from 2006.
