I'm installing a $200 wired 4 camera system in the bus. The rear camera was the main one I wanted with getting ready to pull my toad. The front camera is pretty nice too for those times when someone pulls out in front of you. However, I have yet to install the side ones. I'm not sure where the best place is for them, whether toward the front of the bus, or, halfway back, three quarters back or (?). I really don't have any issues with seeing the rear/side of the bus with the normal mirrors, but it seems like the closer to the front, the more blind things get. The rear-view camera has a pretty wide view, so it seems sufficient for changing lanes with the toad.
What approximate locations have you all installed your side cameras, and have you had good luck with them?
Thanks everyone.
