I use them often... Its still is work, but on rocky ground they sure keep the hide from getting beat up and slides right over the rocks. The hardest is on bare ground.. I modified mine and put pull ropes on both the front and back. If I have help, the back person can help keep it from rolling over or help lift it over logs, etc. I also attacked 1x3's along the outside rails and eye bolts so I can strap the deer in more secure. We get into to more rugged terrain at times. On flat trails and ground, I'll use a cart.....
