I have one of these in my 2010 Wrangler JKU (Actually it was the first on these guys imported for a jeep, the few before were directly imported from Australia). It is awesome. Range anxiety is gone even when towing and out in Big Bend Ranch State park, hours from a gas station. I asked them way back when the bronco was released about offering one, back in June they stated they were looking at getting a vehicle to assess.In case anyone wants the link to the company that makes those tanks. https://longrangeamerica.com/shop-tanks/
They do cool stuff but it is not cheap! Certainly makes some 5 gallon jerry cans look like a good option.
Yeah I have that one also (got it before the LRA) it is an 11 gallon tank that goes with the AEV tire carrier. https://www.aev-conversions.com/product/fuel-caddy/from what I read it's very unlikely that anyone will make a 2nd tank that ties into the existing fuel system automatically or with a switch/pump, since the entire system is sealed for emission regulations.
There is at least one manufacturer that makes an extra tank that mounts between the spare and the truck for Wranglers and you use a syphon to move the gas into your actual tank, I'd be interested in that. Don't like the look of rotopax and jerry cans on a modern vehicle, looks too much like 'mall safari' to me. Great on a classic off roader, but meh on something new. The tank I saw behind the spare was black and you could hardly notice it. Don't recall how much fit into it.
I don't see getting a 1000 mile range out of a Bronco while still having usable cargo space though.
You just need to find a 1050-mile hill.....If you reset the mileage while going down hill . it will give you the 1050 miles to empty.. but only for a few before it adjust it back to normal..
