anyone use a tow bar to pull their blazer? Im looking for a tow rig/dd, and until then i can use my aunts 3/4 ton dodge to get around. But i have no access to a trailer that the blazer fits on. A fullsize trailer is in the planning but right now isnt gonna happen. would it be smart and/or safe tow pull my blazer that is 1tonned on 38's?
