I just purchesed a (my first) GMC K1500 and running the vin check revealed some option/accessories that I did not know the truck had. Anyhow, could someone elaborate as to what the following options actually mean/do: F44 - HEAVY DUTY CHASSIS EQUIPMENT; KNP - H.D. TRANSMISSION OIL COOLER ;K60 - GENERATOR 100 AMPERE.

Not to get you away from this website but these posts are mostly about 2500 and 3500s. Take a look at

for info on all models.

thanks for the link, it helped me get the specifics on the KNP and K60. Still could use some explanition as to how the F-44 HD Chassis differes from the standard chassis
