Have a 30 amp hook up at my office for my old Toy Hauler. Inside my coach on the control panel there is a button that looks like it will let me toggle through 20,30, or 50 amp service. If I get a converter from 50 amp to 30 amp for the plug could I use this. My main goal would be to keep the fridge cold and maybe run one of the ac's a little before heading out on a trip to cool the coach off.

If you currently have a 50 amp coach you can plug into a 50amp plug, a 30amp plug with adapter or a 15/20 amp plug with and adapter for the adapter. Just remember that a 50 amp circuit give you 100 amps of service (50 amps on each leg) so you will have to be much more careful about what you do and do not run. I am currently hooked up to 30 amps in Deadwood, SD but since the lows tonight will be in the 30's I don't think there will be any concerns about the amount of power I require.

Sounds like you are talking about a Auto Load shed system. Knowing the brand name of the control would help answer the question. Does this link answer your question? Intellitec Smart Energy Management System aka Load Shedding System

On 30 amp you may be able to run the fridge and 1 a/c but it will be pushing it. Maybe put the fridge on propane and use the air.

All good advice so far but I think the button you're talking about is probably only to tell you EMS that you're on either 30 or 20... when hooked up to 50 the system detects it and the button has no effect.

My rig has the intelitec 50 amp system as per the link above also.

As Rick said, swithing from 50 to 30 is automatic.
You can use the button to further reduce to 20 if needed.

My coach with run both airs on 30, along with the fridge on AC. It doesn't run them both together, it will run both fans, and alternate which compressor it runs, unless the voltage drops too low.

I have dual air units that draw 13 amps each, fridge draws 3 amps so yes it will be close. Fortunately one will shed if there isn't enough amperage to supply both so the breaker doesnt go.
