Yeah well that 4" of "weird" saved my passenger side door from a tree last Memorial Day Weekend in the Tillamook State Forest!!!
I'm sure the slims look great and work fine, too...but up here in the Pacific NW, the fat ones work better. That's the first I've seen or heard of that kind of flaking; that sucks.
Yes, I prefer my wide ones too, although I have worried sometimes about the width being limiting in narrow places. Maybe we don't need to be there in the first place though.
One cool thing about our wide versions is you can use a high lift under them very easily to lift the vehicle if in a touch situation.
They are also quite good for wandering around the vehicle outside without stepping onto the ground, mud, deep snow, water, etc. with the doors open or closed, or just to get height to the rack without using the inner sill to step up.
I highly recommend the galvanizing though!
