I personally wouldnt trust a hook unless absolutely nessicary. rather use a ball. or attach to the bumper like my dumba$$ did and spend the next week fixing it
These were taken last spring. took me a week to fix it totally, had to have a buddy take one of my brackets to his metal fab shop and fix it cause i broke it. then with a 8ft 2x6, and muscle, and a ratchet i was able to fix it, looks brand new, ud never be able to tell.
