Battery pack might be better really, you could move the centre of gravity slightly lower than the fuel tank and engine on a ICE version.

With how massive the wheels and tires are, maybe hub motors with batteries packed in their centers could work. I don't get the impression that monster trucks strive to minimize unsprung weight, the tires are wrecking balls.

You wouldn't need huge battery life for a 15 minute performance, so shaving off battery weight might just work. What most people go to see is airborne jumps rather than crushing things hence need for low weight.

It's the weight of the batteries to drive that sort of power compared to ICE that would be the issue, not location. Would be an interesting experiment
