well, that says it, Q thinks its looks dumb, nobody do it.
the rear collision theory may be a bit flawed, I mean if you are backing into something that is hitting you above the bumper, you are gonna have some nice damage anyway. I guess it is a matter of the way it may look. I mean I am not goign to put a 2500.00 set of rims on my ST mostly because of the damage that can result from hitting a curb.
To make it really stable, I guess you would want the swing gate to attach to the frame, but lord knows what you would be getting into then.
Just an idea. maybe when mine has 150k on it and its a hunting/fishing vehicle, ill give it a shot.
