2024 Ford F-150 — second battery versus portable power station

RotorWrench276Community StarterDec 2, 20252024 Ford F-150 Lariat 3.5 EcoBoostColumbus
2024 Ford F-150 Lariat 3.5 EcoBoost, about 34,500 miles. I want reliable fridge/lights/device power for weekend trips without making the vehicle electrical system unnecessarily complicated. When does a hardwired dual-battery setup beat a portable power station?

I'd want a measurement, not a hunch. Get a real battery/charging test on the 2024 Ford F-150, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. Happy to compare notes if your setup is different. That's my plan before I call anyone.

This is usually cheaper to test than to guess. Two 2024 Ford F-150s can feel identical and have different causes, so measure before you copy someone else's repair. You'll know quickly if you're on the wrong tree. Happy to compare notes if your setup is different. Wrote this up on my lunch break.
