BOTH... see the link.. $20. Runs on 9V batt. or can plug into power outlet with garage door opener. It's motion activated and turns off automatically. Startling for passengers who see the red laser dot suddenly appear and think someone is aming at them...
If the truck was for me, it wouldn't even be a thought in my mind. But since the wife will be pulling it in and out, the sound of a mirror ripping off gives me chills.
I pulled her car out today, and it seems like there is plenty of room. The 4Runner is only a few inches wider, but like the previous post stated, I feel the mirrors could really add some width.
