Dang...I guess Im just doing it the hard way! I carry mine by myself, usually with the 3 extensions already put together with pins (16 ft.), lean it against the tree, climb up it (carefully) and strap the top. Then once the top is strapped I sit down and enjoy the view before climbing down and strapping the support to the ladder.
Usually takes me a whole 10 minutes. I guess the 2 man stand is a bit heavier, and may need another person to lift to tree. It probably would be more difficult if I was putting the strap around a 3 ft diameter redwood tree, but the ratchet end is usually heavy enough to swing it around. Watch out though and dont let it hit you in the eye!
My climber weighs a whole 20 pounds and straps on my back. I guess that is why it is my favorite. Its portable and easy to climb...to whatever height I may want to hunt! It wont work in all trees, but I hunt in hardwoods and poplars are very abundant. Nice straight trees with 20-30 ft of tree before the branches start.
Best of luck...and think positive! You can do it!
