I purchased a Pack-a-pull last year and was lucky enough to use it last fall during the Idaho Elk season. Our elk went down on the south face, but only about 400 hundred yards from a dirt road. While taking the elk apart I hung a front and hind quarter on the north side of a tree to pick them cool, as deep shade was not available on the south face of the mountain.
The pack-a-pull system worked flawlessly and made easy work with hoisting the quarters up off the ground. Had we been 4 miles instead of yards away from a road the system would have been an absolute life saver. In 2012 I killed a big bull 4 miles out and we did or best to lift the quarters 7 feet off the ground and payed that predators wouldn't find the meat over night. With this system you can lift your quarters 10, 12 feet and higher if you've found the right tree.
For the price and the weight of this system you just can't go wrong. I recommend this product to everyone.
