NO SIR IT'S NOT A CHEVY.
Welcome from New Mexico! Nice truck love that blue! OBS is "Old Body Style" which is what these trucks are referred to but we try to stay away from that terminology because it gets into this NBS, NNBS (New Body Style, New New Body Style haha). So we try to stick with the platform name of GMT400, GMT800, GMT900 and so forth
