Norcold 1200 ammonia top up?
We're 12 days from the end of my winter trip; then I will have all the time in the world to deal with the fridge. I'm just trying to make it last the next 12 days. About a week ago, the fridge stop...

You can't just "top off" the ammonia, no. It's actually a mixture of a few different things in the cooling unit: water, ammonia, hydrogen gas, and a corrosion inhibitor (which isn't directly involved in the cooling cycle). The whole works is under rather high pressure.
It's doubtful that just some of the refrigerant has escaped; more likely in my opinion is some other sort of problem, maybe debris blocking the ventilation airflow, or some control problem, or the door not sealing properly, or frost and ice buildup, or the cooling unit getting clogged (which isn't really repairable).
If you had an ammonia leak and were around at the time, you'd be well aware of it! You could usually also see the chromate residue left behind.
