I really don't mean to turn this into an all Bobcat off topic discussion forum, but just thought I'd share this little mod I did this afternoon to Bob.
I bought a little rear view camera/monitor system off of ebay for about 70$. The camera is waterproof, not sure about the monitor, but I really don't think it will get wet where I mounted it anyway.
Camera mounted on the back. I think it's meant to attach to your license plate bolts. I drilled and tapped a couple of 1/4-20 holes and just mounted it.
Monitor mounted inside
And my lovely demonstration model
