Maybe a Grand Cherokee the wife had a Cherokee and it was a hot bag of problems not even the same class of vehicle. If you want fuel capacity other Suv’s not in the off road category to choose from since you mentioned the Cherokee I don’t think many would consider that for what the Bronco is meant to do.
Thats actually kind of doable, however I think the only way to make it happen is diy because of potential liability in a rear end collision. Just poking around w/a tape measure, and looking at a few already available race cells, I can make room for as much as 10 gal, maybe more. W/the muffler heat shield removed, and the plastic storage tray removed, there's quite a bit of room w/out the tank protruding below the frame rail or bumper. How to fill it, and how to pump it to the main tank are more complicated. I think using a second lift pump and switching arrangement would add cost and complexity that I don't want, but a simple arrangement that refills the main tank from the auxiliary would work fine for my purposes. I would also like the auxiliary tank to be relatively easy to remove when not needed. Its an idea a few of us have tossed around, but really haven't gotten anywhere with.
