This is one for the books but I am going to ask it anyway. Maybe it will bring a smile to soemones face or make you thank god your not my neighbor or freind. I have a 07 1500 5.7 and was wondering how to tell if the hemi is equipped with mds? I bought the vehicle used and didnt ask if the vehicle had it because I read somewhere that this wasnt available until 08. I was just wondering if there would be a light or some indication. I will ask the shop or dealer but was wondering if there was a quick way to tell? Thanks. I am off to obtain my masters in mechanical engineering and then applying to chrysler!!!
