For the Durango there is no "decoding" of the VIN number per se. The only thing you can get from the Durango VIN is the model, engine cylinders and AWD vs RWD. For example...
VIN: 1C4SDJH98MC603675
1 = UNITED STATES ASSEMBLY
C4 = DODGE
SD = V8 ENGINE (RD = V6)
JH9 = SRT HELLCAT (HDG = GT PLUS, JET = CITADEL, HCT = R/T RWD, JCT = R/T AWD, JGJ = SRT 392)
8 = CHECK DIGIT
M = 2021 (N = 2022)
C603675 = ASSEMBLY SEQUENCE (DODGE does not build in VIN order)
