They were doing a story on one of the national morning shows, I think it was the one with Katie Curic, anyway they had about 5 different types of vehicles that they were testing blind spots with. The first one the tested was the Avalanche. Needless to say it was the worst! They placed 2 cones behind the Avalanche and had a woman setting in it. They kept moving the cones back until she could see at least 1" of the cones by looking over her shoulder. They ended up something like 66' back from the Avalanche before she could see them, much further than the other ones they tested. I think we were all aware that the Avalanche is not the best truck as far as rear views go! I raised the front of mine to level and it is much better but you are still going to have less of a blind spot in a sedan!
