Rear-view mirrors for Ford Explorer

Just took delivery of 2010 Elkmont and noticed that traffic visibility to the rear is insufficient for high level of safety when hooked up with my TV: 2006 Ford Explorer. By being observant and planning well ahead of time I had no issues getting it the 50 miles or so home...but that was on familiar territory. And backing up was a bit of a challenge as well. I know there's at least one other member with an Explorer here. Perhaps they or others could chime in with what they might reccomend. I certainly could use a solution, because there are times when I would be traveling and might REALLY need to see what is behind/alongside of me!
