I took this route as well (I used different lamps, but the end result was the same.)
I now have true LED headlights ( https://www.amazon.com/gp/product/B09N79VG65 )
and OEM LED foglights.
The LED headlights are really much better than sticking LED lamps into the OEM halogen fixture; the low beam...
I've read that the Carlinkit v. 2, 3 & 4 all use the same hardware. The v.3 has a different interface than the v.2. I haven't tried v.4.
Version 5 has both CarPlay & AndroidAuto in one box.

Different locations...
Different altitudes...
Moving or stopped?
And you can't verify outside temperature (or other weather conditions.)
So yeah,

If you're pulling that much current all the time, small wonder you cooked the aux. battery and see 14V nearly constantly.
Thousands? And you've seen them all?
Out of how many hundreds of thousands of vehicles?
And that's just Jeep. They're not the only manufacturer to use a similar design...
Into service September '20.
Not driven regularly.
I use a maintainer if it's going to sit for more than a week.
I use the ESS as intended.
Original batteries with no issues.
I probably just jinxed myself...

Well, that didn't work out so well...
One of the fittings broke at the disconnect, and the other popped the fitting out of the hose.
So I tried a variation on the hose-through-the-grommet method...
My RV uses a similar configuration: that's where I got the idea. It's a bulkhead fitting...
All the unbelievers...
My Sport S, with 18" stock wheels & tires (from a Mojave,) gets 23+ mpg combined, as long as I drive conservatively.
I don't see why his 19, even with bigger tires, is so hard to believe.

Tire temperature, fill-air temperature & humidity will affect pressure & readings.
Your on-board compressor is pumping through whatever is outside the truck, and increasing the fill-air temperature.
The dealer is using a very large compressor, which doesn't raise the fill-air temperature much...
Studies have shown that a tonneau cover doesn't have a lot of effect on drag, as the airflow over the cab bypasses the bed.
With a cap (topper), I'd think you'd actually generate more drag, due to the vortex created behind the large flat rear surface.
But I'm not an airflow specialist, either...
