    Few RPO's decoded

    AJ1- Deep window tent RR
    KC4- Engine oil cooler
    GT5- 4.10 gears
    LQ4- 6.0
    M32- AT 4 speed HMD 4L60E HD
    NP3- AWD transfer case
    NYS- 4 wheel steer
    Y91- Luxury edition
    Z82- Trailer provisions special equipment HD
    Z88- Brand GMC

    The rest of the RPO's are not that interesting to me.
