    While I have a hitch I don't have a tow haul button, (4.8 liter engine) and most likely need to replace my alternator to help run the Ecoflow 800W Alternator Charger, (the name can be misleading as it's an inverter to charge their power supply/products).

    Any brand recommends?
    150 will do but the margin of a 220 might bring peace of mind.

    RockAuto would have the best pricing on it

    Considering the level of hassle the r&r is and that the 180 amp oem is under 400, that is what I got.

    Thank you for the responses and I plan on stopping in at a local Pep Boys where, for $15, they'll have a look and tell me what kinda alternator it is.

    Here's a screen shot of Toyota's deets on my vehicle which...I woulda thunk...it had the 150amp alternator.

    Update: went into Pep Boys but they have to see a stamp on the side of the alternator to discern what it's rated for.

    Always learning...
