Back up camera
I think the backup camera works well enough. During the day it adjusts for brightness of the ground. I don't recall any problems at night. I'll look next time I'm backing out at night. The lens gets blurry if it gets wet and dries. The water here in So Cal is very hard, full of minerals, and that may be why.
One thing I learned the hard way is that the camera points down and does not see level, much less up. I was watching my monitor one day while backing up in a parking garage and ran smack into an overhead pipe that hung down. It bent in the back bar on my Baja Rack. Unlike the standard flat utility rack, I paid extra for a straight back tube. It misses the shark fin and makes it easier to load lumber and gear. That back bar bent in to almost touching the shark fin. The pipe would have taken out the shark fin if it weren't for the straight rack. Cost me $50 for a welder to replace the section of tube. Cheap lesson.
