It's definitely working, I can change the 'colder' knob, and you can feel it click and cut the AC to just air. I'll experiment tomorrow, hoping that if I don't have the cold as far as it will go on 'colder', the AC will cycle on and off as it should. I've just always ran a camper AC as cold as it will go, all the time. Maybe I can't do that with this one? I don't think I've ever seen a camper AC run as cold as this one.
If it's still showing ice on the lines and compressor, then the one poster above is probably correct....It's low on refrigerant and probably will take a dump on me.

I think the aluminum "wire" in your picture just to the right of the connector is your thermostat.
It monitors the temp of the air coming back into the AC and turns the compressor off when the temp reaches the setting of the knob.
If you turn the "colder/warmer" knob down (that is the thermostat) to minimum and the unit does not shut off after it cools the TC, then the thermostat is bad.
The unit can freeze up if the humidity is high and it isn't cutting off.

If it ices over before it reaches the set point of the thermostat it's most likely low on refrigerant.

I think you're barking up the wrong tree. Your AC should run until it reaches the preset temperature as determined by the thermostat knob, then cycle on and off as the temperature rises and falls.
It should not be running that long, freezing you out, then freezing up. Initial run in a hot camper may be a little longer but once cooled down it should not run more than half an hour at a time unless it is severely hot and can't keep up. Since it is freezing you out, it obviously is not severely hot, and has no issues keeping up.
The most obvious cause is your thermostat is not working. However, is it possible that you simply are not familiar with how an old analog AC unit works? As you turn the thermostat knob, the wider the line, the colder the setting.
When I set my AC, I simply turn it to max cold, let it run until the camper gets to the desired temperature, and then turn the knob back until the compressor shuts off. Then it will cycle on and off to maintain that temperature.
