One of the benefits of sliders that many, and I mean almost no one realizes is the side impact protection provided.
I was T-boned once and all that needed was to have the passenger side rear door replaced and the strip molding on the passenger side front door, and of course the right side slider, which insurance purchased me a whole new set.
And for those who have wider sliders (talking about myself here), that stick out a little further, it helps with not getting door dings from idiots who like to obliviously swing their doors out when parked. Their door gets dinged on your slider instead of you getting the dimple in your door.
