I too find the lack of a 12v port annoying. I have a Garmin RV GPS and a 360/rear view camera system for my 5th wheel. Both came with 12v ports. I ended up getting the hard wire kit for the Garmin and wiring up a 12v port for the camera using one of those fuse taps mentioned earlier in this thread. On the two internal fuse panels i only found one fuse that was switched power and it was one of the 3 legged ones so i had to get a tap for that off Amazon.....

 

Patiently awaiting availability of the upfitter switch kit for a Denali.

zero interest in a CD player here.  Had one on my 2016 and never used it once.   But I used the 12v power outlet for my RV camera system a few times a month.  We leave on a 4000 mile trip ne

The bumper 7-way has a live 12 volt circuit. I rigged up 3 of these for my trucks to backfeed a battery maintainer during the winter months when 1 or 2 might set for a month at a time.

Put the 7 Way with 12v. Cigar lighter on the bumper 7 Way for a few hours, with cell phone charger. Power did NOT time out.  Also turned on bed lights from dash switch. Timed out after about 10 min.

I know it’s an older post but put together a 7 way trailer plug for charging. I have two Battery Tender Jr’s and one Battery Tender Plus. I only ever use two of them at a time and used the ring lug connections. 
 

I took one of the three alligator clamps that I wasn’t using and cut it below the fuse holder. Used a Hopkins 7 way trailer plug from WW. Put it together and works good with my 2018 1500 with 2 of the maintainers. Don’t have a pic but looks like the one gemarsh posted.

 

Will work on getting a 12v outlet in the cab whenever my AT4 HD arrives.

 

Edit: Added pics.

I had a similar setup I used on my 2021 but I was advised not to use it on my 2024. I instead hard wired a NOCO quick connect plug to the battery and just plug it in there.

Update: The 7 way trailer plug that I put together to charge my battery was for my 2018 1500, the trailer plug 12v was connected to the main battery, did not have an aux battery. I found out after getting my 2024 AT4HD, the 12v at the trailer plugs are connected to the aux battery. Won't work anyways!

      Clunk when putting truck into drive and reverse.

      By Matt Parker · Posted

      I have a 2000 Silverado 1500 LS, whenever I put it into reverse and also in drive it clunks, the truck also feels sluggish when driving. Any advice/ideas ?

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
