Tow points on a 2006 Dodge Durango SXT?

So I have a 2006 Dodge Durango SXT. It doesn't have a trailer hitch or designated towing hooks. I was wondering if there are any safe places to attach a chain or a tow strap to on it so that I could pull out friends cars who get stuck in snow, or off road somewhere. Also, if anyone knows where I can get a tow hook or trailer hitch for relatively cheap and somewhat easy installation, please let me know. THANKS!
