Yes, I use the stand as a frame pack. Only for hauling in the stand, sticks, and a small backpack. It is not used as a meat hauler. If I shoot something I quarter it up, haul all my gear out, and return with a dedicated meat hauling frame pack, which is more suited to that task.
For the attachment point between the xray straps and the stand: There is one long 1” webbing for the shoulder straps. It is doubled back on itself and held in place by tri-glides. The doubling back of the 1” webbing onto itself attaches the shoulder straps to the treestand and also provides a 1” strap handle for picking up the whole thing, as shown in the pictures. No sewing or special buckles required.
