Well, since I have personal first hand experience here, I wanted to share it with everyone. Back in very early 1998 I was involved in an accident. I was driving my 1987 Ford F250 Diesel with a semi-heavy duty front replacement bumper. I say semi-HD because it wasn't anywhere near as heavy duty as the Denver Off Road bumber I am getting for Godzilla (like the one Earthroamer has). Anyway, it was a rainy, slippery night and I came around a blind corner to find a red traffic light at an intersection and a mid 1980's Honda Civic sitting at the light. I locked up all 4 wheels, but since I was going 25 MPH and there was less than 60 feet between me and the Honda, I ended up rear ending it. I caved in the entire back end if the thing, and mangled my front bumper pretty good, but otherwise did no damage to my truck.
Well, even though the young girls in the Honda all got out faster than I did, and all claimed they were uninjured, several months later I was served a lawsuit at work from the accident. The driver's parents had decided to sue me. At the trial, I specifically asked my lawyer to ask all the prospective jurors if any of them had any type of prejudices against "those big, heavy vehicles" like SUV's or large pickup trucks. They all said "no". I attended every moment of the trial, and not once did anyone on either side bring up the sizes of either vehicle or anything related to my bumper, or anything about either vehicle, except to state for the record what types of vehicles were involved, who was driving, etc.
And this was in great liberal, litigation crazed California!
So, in this case at least, my bumper had no bearing in the case at all.
