I got a new 2011 3500 4X4 crewcab
ST with a 6.7 in March. I already have more than 21 k miles on it
I love the truck
Very poor headlights.
Can an ST be upgraded to quad lamps? I know the parts are expensive, but not as costly as a wreck. Do I have to replace the harness too? What about any switches or controls / computers?
