Looking for long term feedback from anyone who is running a smart alternator..........

and dc to dc charger for aux battery systems. Wondering if anyone has had any negative effects on smart alternator or new vehicle electronics in general. Our platform is a 2023 Chevy Colorado ZR2. Bought new and currently has 12k miles.

Thanks for the feedback.

No personal experience but there has been a lot of discussion on some RV forums I read. Folks add the dc to dc chargers to ensure a steady charge to travel trailer house batteries via the 7 pin. Left to their own, the smart alternators often don't do much. I haven't read of any downsides.

My 2021 JLUR has a DCDC charger that keeps the 100Ah LiFePO4 battery charged when the engine is on.



It also trickles power to my 2024 nuCamp T@B 320S BBC camping trailer over the 7-pin, thanks to the Tow Package, it is a 240 AMP alternator.

I need to disconnect the 7-pin when I'm stopped for the night, to prevent the JLUR starter battery from draining.

I haven't been able to sort out whether I need to get an Isolation Relay installed so I won't have to unplug the 7-pin anymore. Over my head.

I’ve got 68k miles with my set up and no problems at all. You’ll be fine.
