2020 Toyota Tundra — second battery versus portable power station — buyer question from Miami

DealTuner471Community StarterJul 6, 20262020 Toyota Tundra SR5Miami
2020 Toyota Tundra SR5, about 101,000 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? Interested in real owner experience more than guesses.

I'd keep this practical. Verify the cheap/easy branch on the 2020 Toyota Tundra before a big repair or a big spend. That's where I'd start. Happy to compare notes if your setup is different. Worth doing even if the car feels fine right now. Doing the boring step first on purpose.
