Dealers told you? Well of course they're not going to say their bumpers fall off - DUH! Reminds me of the tire dealer who claimed he never saw a Carlisle tire failure.
You can do a search on here about the subject and read about people like ME, who actually had a bumper torn off that mighty solid steel frame. We tell the story in an attempt to keep others from suffering the same fate. You don't sound like the type who wants to learn from others experience though and you even sport a chip on your shoulder for it for some odd reason.
So go for it.
