    Hey guys my 04 Silverado has the light duty power package and I was wondering if anyone had any info on what exactly this package includes/ what it was meant for (towing, offroad etc.)
    I know it has a factory rear locking differential, "HD trailering equipment", 3.73 rear axle, and "heavy duty suspension" (items in quotation are from the window sticker)

    ...not certain but I think that package consists of "the 5.3L and HD trailering" options

    Usually means the 7pin connector with the wiring already with the truck for an electric brake controller. and there might be more but i know that is part of it, since i had the same option on my 02 when i bought it.

    I think the HD also gives you a larger transmission cooler.

    I forgot about that, it is the external instead of the internal cooler.. Usually a good thing for your tranny.
