Mine was like swiss cheese... it was really bad, mines a 97 and a michigan vehicle. I bought a replacement rocker from lmc, not too cheap though for just a piece of steel that's almost guarenteed needs some shaping to make it fit correctly. I can guarentee that under the door is bad and right infront of the wheel well is bad, just like mine. IF you don't get all the rust off that you can it'll show back up within a year... just like mine is. If you take off the fender flares, there's holes that will need to be filled, for thats what holds the trim on.
