Tom- I talked to Jeff Mohr today at superbumper.com. I think I'm going to order the 24" wide. It'll only stick out 3/8" more than the 18", so that's no biggie. Also got an email from him (kind of like a mini newsletter type deal, talks about the latest testimonials). Said only 14% of rear end collisions will MISS the superbumper....oh gee, aren't I in an exclusive club!
