Wecome to the madness...it's a good thing and only hurts a little...

A good back-up camera is only a few hundred dollars and can save you that much and more. I have one and many of the other members do also.

Ditto on the spot mirrors, just make sure you get the smaller ones. I had the larger ones on mine when I bought it, but it obstructed too much of the regular mirror, so I changed them. It's much better now and is a better balance between the regular view and the spot.
