Greetings, all. I'm still learning here and am wondering about something I ran across recently. (Sincere thanks to everyone on here who has already been a huge help to me thus far!) I understand that the increased-power/heavy duty alternator (part number 22949467) appears to have made its way into many 2015 CrewCab models and other models with the snow plow-prep package. It seems tied to RPO 5W4 (which, in several sources I've researched, ties back to "VEHICLE SPECIAL SERVICE, MUNICIPAL" - makes sense for a snow plow-prep package). I scored a fantastic deal on one of these units for my 2014 Silverado LTZ Z71 DoubleCab 4X4. Being an LTZ, my Silverado has most of the current-drawing goodies. It also is about to have the factory Kicker subwoofer upgrade kit, an on-board air compressor (Viair 40049) and a full front/rear dashcam set-up with active/passive monitoring. I've also just paired all of this with a brand new AC Delco AGM deep-cycle higher output battery (P/N 94RAGM). In other words, all of the further current-drawing goodies are here and ready to be installed when the weather here gets a bit warmer. Are my electrical upgrades going to be good enough to support an already high current use truck with an extra draw or three?
