It's best to minimize the amount of air below the cap, so topping it off up to the ring that the cap seals against is best BUT if you've just replaced the coolant, there's likely to be air elsewhere in the system anyway. Some vehicles have a defined bleeding process you have to follow to get the air trapped in high points out (usually the cylinder head and ...

Because you live at a high altitude, you may want to consider getting a thermostat which opens at a lower temperature.
If your thermostat is rated at, for example, 195 degrees F, it will begin to open at 195. It may not be fully open until 200 or 205.
As you say, water boils at 200 degrees F (94 C) at an elevation of 6000 feet (1829 meters). Thus, your ...

One possible solution (to the symptoms) may be to upgrade the size of your radiator. Base-model trucks typically have a 1 inch radiator, but models with larger engines or "tow packages" will often have a 2 inch radiator. In my experience, radiators will use the same mounts, making swapping rads relatively easy. You may also have to get a shallower fan shroud ...

I. Solution: I had the wrong thermostat. Not sure how this happened. It was too long and even though it tested okay on the stove in a pot of water, it didn't have the space to open properly in the engine. So problem solved, finally! Thank you to all for looking at this.
II. To help diagnose an overheating engine, brake it down into these steps:
First, ...

You've checked almost everything there. Perhaps check the vehicles heater radiator for blockages which can restrict flow around the main system.
Is the vehicle ACTUALLY overheating, or is there perhaps an electrical fault showing an overheat condition e.g. faulty temp sensors, gauge etc.

A clogged catalytic converter will cause back-pressure in the engine, and cause the engine to run badly - you'd have trouble reaching 35mph with a bad clog, and it wouldn't just be on hills.
You've already tested for one head gasket issue - unfortunately, on older Subarus, that's always the first thing to check for! You have no exhaust gas in the coolant, ...
