The Southwest Fabricators are very similar looking, but I just called them and they have to be WELDED to the frame. (I knew I had ruled them out a long time ago but couldn't remember why) I like the fact that the Tough Country are simpe bolt-on design.
On my 03, I don't want to weld something on. Maybe on my 94, but even then, I like the flexibility of being able to un-bolt it if something changes down the road.
