Recommendations for high output alternator for 2019 model year?

Any recommendations for a high-output alternator for a 2019 4Runner? The 270XP from DC Power Engineering looks good, but it is compatible only up through the 2017 model year.

I'm definitely not an expert but I'm pretty sure there are no mechanical differences at all from a 17 to a 19. I'd imagine that alternator would fit without an issue. Again, I really have no actual clue so might wanna wait for someone smarter to comment lol

I actually bought a 270XP from Nations Starter & Alternator. But they mistakenly sent an incompatible alternator which physically would not fit. I returned it and Nations kindly gave me a refund. Kudos to them for that.

Nations said they would be able to make a 240A version, which I would actually be quite happy with, but apparently it would take a fair amount of time. I believe this would be the first time for them developing this particular model, so I imagine it would require some time for product development and testing.

Unfortunately, DC Power Engineering said they currently do not have any plans to make a high output alternator compatible with the more recent 5th gen 4Runners.

curious - why do you need one?

On road trips where I will be sleeping inside the vehicle, I will have various electrical appliances powered by an auxiliary battery. To recharge that battery, I could use solar panels, but a DC-to-DC charger that draws power from the alternator doesn't require sunny days, and can charge a lot faster. For example, the Redarc BCDC1240D can produce 40A of charging power, compared to only around 5 or 6A from a 100W solar panel.

Pulling this much extra power would overload Toyota's stock alternator, but a high output alternator can easily handle the extra load.

A good thread on the topic is:
