We hang moose and caribou from a portable meatpole made of 2X4's and folding sawhorse clamps.
Our setup is 4 12 foot 2X4's for legs, and one 2x6 for a crossbar. Lay the crossbar in the clamps, spread the legs and stand it up. We the nail a couple of shorter 2X4's to the legs for braces and it's all ready to go.
