I have the same chrome strip on my 2012. However I removed the bumper chrome and the headlamp bezels and had the bidy shop I used to work at paint them to match the body. The chrome just didn't look right!
BTW, I found out that 2012 was a half year. The early ones had the chrome in question, they were considered the Limited model. The later 12's got the new style front end and all the other updated items like outside TV, drop down bunk etc. if they were XL's they got the full size baggage doors and 22.5" wheels.

Better to have a bad day of camping than a good day at work!
