The only problem with 14+ is the hd models are still nnbs for 14. Im having a hard time finding things for my 14 because of this carry over. The k2 designation will work once it catches on according to gm the xx part is cab size ie. K2CC is crew cab K2DC is double cab and K2RC is reg cab. Not to make the k2 designation even more confusing or anything. Lol
