I bought a West Coast Trucker Mirror from the local auto supply store and mounted it horizontally under the canopy. The mirror mount is quite solid so I don't get vibration unless it is really rough ground. The mirror is nice and wide so I have a good view of what is behind me and can back up easily without getting a sore neck. I have been doing a lot of backing land clearing 3 acres so it helps a lot. Here is a couple of pictures if anyone is interested.
