How Does a Converter Hold its Voltage?
A solar controller uses PWM but how does a typical RV converter do it? How much play is there up and down to hold it there? I have a 12v mystery draw I am chasing down, but in the middle of this, ...

Voltage regulation and ripple very from manufacturer to manufacturer. In general, "you get what you pay for".
In general, there are two types, linear and switching (PWM is basically switching). Most every DC power supply built in the past 20-30 years uses switching technology because it is more efficient and at least in the last 10 years or so, probably cheaper.
Switching does not guarantee better regulation and less ripple, but it is much more likely.
