Sierra 2500 SLT 6.6L Duramax

  • Automatic transmission
  • 55,400 miles

Outer rust on rocker panels on each side. Body shop says it's coming through from the rear. $4100 to repair - replace rocker panels. Body shop says this is common - a bad design for this year. Painted with aluminum Chassis Saver for now, but not a permanent fix. Can expect that once the panels are replaced, the same thing will happen 7 yrs later.
