Most wranglers don't see proper off-roading, none of the crossovers. But even though, you have the whole front trunk where you can add a range extender (similar to BMW i3). You can strap extra canisters - range is not an issue.

What you've got is a superior off-roading machine. With 4 electric motors you can apply torque with extreme precision. Increasing ground clearance is not an issue since you don't need a drive shaft and diffs.
