Default Losing coolant....head gasket?

2000 mazda b3000 3.0v6 4wd 185k

So about a month ago i started to notice that my coolant levels were dropping about a half gallon every 3 days or 200 miles. Thought it might just bee a leaky hose, i inspected the entire engine bay and not a drop. I thought Could it be just evaporating? as my mixture isn't currently 50/50 (coolant is expensive and its not below freezing yet here) Recently i noticed liquid dripping from my exhaust at a rate that with my minimal technical experience i figured to be excessive, and it seemed more like steam then exhaust smoke. Could someone please take a shot at a diagnosis? best case/worst case? Any additives that can prolong the inevitable? Any tests i can perform to diagnose myself?

Try checking the oil and see if it's runny. I have the same truck and my heads went out and lower intake.

I started losing coolant, and it was the thermostat housing. It was cracked. Replaced it and all is good now...worth checking out.
