3 MP should be fine, just select macro so it can focus up close in, the res should be ok, its just out of focus.... Then upload the full sized image and post a link to it, so as to not kill anyones connection when they check out this thread.
i'm curious about that round disk at the end, and chance it could be a sonic sensor and that its part of a wireless back up device? not unnecessarily for making a beeping noise when you back up to warn people, but maybe something that would have been linked into a device in the cab that would tell you when you are about to hit the cube van parked behind you.
For clarification, how long have you had the truck, are you SURE it wasn't there before you bought it, what do you do again?
