I have experience in the two man ladderstand. Hope this helps you. It takes at least two to raise one of the doubles. What I do is attach the center ladder support after I stand it up to the tree. The center support on mine are adjustable metal tubes, one side clamps to a ladder rung and the other attaches to the tree with a ratchet stap. It then makes it more stable to climb higher. Once at the top I start attaching other ratchet straps around the tree to the railings of the platform. Mine are only 15 ft. stands so while I'm up there I have a person on the ground with a pole saw bringing the one side of the strap around the tree for me to hook up and help keep the strap from twisting. I buy better ratchet straps from a farm supply store and toss the others that came with the stand in my tool box to use on something else. Like I said, this is for a two person stand. Good Luck
