What Tom said.
If you want to know which of the two compressors is low, then open the hatch where the circuit board resides. Put an ammeter on one of the leads going to each compressor. If it's not pulling 12 amps or more in hot conditions then you are likely low.
When the charge is low, the temperature of the evaporator coil actually falls below 32 degrees. Blow humid air across a piece of metal less than 32 degrees and there ya go.
Tom is also right in that the SCS units came from the factory sealed with no service ports. Unless it's been worked on and ports added, you can't check the charge with gauges.
If it ices, turn the unit to fan only to melt the ice as rapidly as possible.
The biggest source of water inside the coach is the shower. Use exhaust fan when showering and wipe it down good after to reduce the water in the air. Every little bit helps when it's hot.
