Correct, theoretically the engine would labor less as the rpm range with higher gear ratios whether via smaller tires, ring & pinion, or transmission gear changes as it'll be nearer to the peak torque. Peak tq on the VQ40 is at 4000 rpm though so you will have to give it some gas on the uphill, but not as much, and it may actually be healthier for your engine to run a higher RPM when towing anyway so it's not lugging. As you said, fuel usage will be dependent on terrain and hills. Your Pathy will most likely guzzle more fuel on flat land due to higher rpms, but will guzzle less on hills. It's a trade off or compromise.
