towing mirrors 2010 jeep liberty

I'm looking for mirror extensions for my Jeep, really just for peace of mind when changing lanes. My TT isn't very long, but it is wider than my mirrors can see, so I'm almost completely blind on the sides. I like the look and ease of the CIPA custom slip-on extensions, but can't find a specific one for the jeep. I'm thinking maybe one of the Dodge ones would fit, as they're both Chrysler vehicles, some have similar design/body etc. Anyone try this? Or a recommendation for a universal mirror? Thanks!
