It shouldn't be used up - at least not at any quick rate, though it can burn or be subject to some evaporation over time in severe heat conditions. Having said that, the operating temperature of power steering fluid should be a lot more stable than that of, say, brake fluid that could have occasional extreme stressors, such as trailer towing or lots of steep downhill braking.
The biggest issue with many vehicles is that power steering fluid is often the same DOT fluid the brakes use. That stuff is very hydrophilic, so it needs to be replaced at regular intervals to keep water out of the system. That's why you should only use a fresh, sealed bottle of it when doing a change and (in the case of brakes) should do a full bleed of the old fluid. This will also remove any air that makes its way into the system.
It doesn't sound like that's what the fluid is in the Jeeps, though it may still have the same hydrophilic tendencies.
I can't believe any system would consume that much fluid without some sort of extreme heat of friction stress like you get with motor oil.
Unless this system is really bizarre (like in a bad way), the only things to watch out for are leaks, water or dirt infiltration or heat related stress (which would likely cause obvious discoloration).
