I can tell you the EcoFlow Alternator works great on my Bronco with the 2.7 engine, I use it in conjunction with a EcoFlow battery to power my Dometic fridge. But Dude brings up a good point about not knowing the charging system on the BS. You can dial down the amount of watt's it puts out which...
Having a full size Bronco as well I can say if you were looking for an SUV then getting the Jeep Cherokee was a better choice over the full size Bronco, they really are apples and oranges.
At least the Sunbird had rollup windows :)
The TR3 was a cool looking car though, the only Triumph I ever had was a '81 TR8. Had the Rover/Buick 3.5 liter V8.
You must be a glutton for punishment. I have Sync 4 in my Bronco and Maverick, the Sync 3 in the BS feels like something from another era which of course it is.
