i have an older 8x8 magnum and want to put a canoe rack on it.i was thinking of making it out of 1x1 box tubing and angle iron to skirt the body my question is can i use this rack to hoist a moose or elk into the back if i turn my winch around add some rollers on the top.will the plastic on the argo hold that much weight if i have my angle iron on the top and put a piece ot flat iron on the bottom and then bolt it through both every couple of inches.
