I've had my 96 ZJ with the 5.2 for about 6 months now and after I replaced the thermostat that's exactly the behaviour mine exhibits. I've done in-town and highway at ambient temps from 60 to 110 with little to no change in temp gauge reading.

Not sure it makes any difference, but I'm at about 5,000 to 7,000 feet elevation all the time, too.

That's a little high. Flush the fluids and clean the radiator. That should help.
