The previously mentioned items for identification are all correct.
In addition, 4th gen Ram 1500s (2009-2019) are product code DS, while the 5th gen 1500 is product code DT.
As of today, if the 11th digit in the VIN is the letter "N" (Sterling Heights Assembly Plant), it is a 5th gen 1500 since no trucks have previously been assembled at Sterling Heights.
4th gen Rams will either have a "S" (Saltillo, Mex) or a "W" (Warren Assembly) as the 11th digit.
