Someone on here would know the numbers I'm sure.

You make a good point. I grew up in the 70's during the "Panel Van Craze" and it seemed like there were millions of them everywhere. The funny thing is that nearly everyone pulled off the stickers or ordered them without because the 1st trip was often to get murals painted on the tailgate and sides.

Most Sandmans were modified heavily and subjected to some horrible "custom" atrocities, and yet as you say, there seems to be a lot still around.

I guess a lot of tags survived and have been given a new body in a lot of cases.
