The cameras mounted are a bit of a novelty for a lot of situations, IMO. They are worthwhile if you can put one to use. I was loading trucks in a closed shoulder between a barrier lineup and the guardrail. It was nice to know where the tracks and ass of the machine were without getting out the of the machine. The blind side of the hoe was closest to the barrier, had to travel in reverse totally blind as I wasn't able to swing around to see where I was headed. Had multiple trucks coming in and had to walk the hoe 150 feet down the shoulder to let another truck into the lane, a real hassle to say the least. I was working alone with no spotter and live freeway traffic outside the barrier, the camera helped quite a bit with that little gig.
