You may have plugged your motor home into a home outlet that is also on a circuit with another appliance. That would cause the home breaker to trip if the total load on the breaker was exceeded. Plug your motor home into an outlet with nothing else drawing power from that circuit. Make sure to use a heavy-duty adapter and short heavy duty extension cord. Try to start the AC again.
If it still trips the breaker, replace the capacitors with the original capacitors. See if the original problem returns. If it works, you may have wired the replacement capacitor incorrectly. When replacing capacitors, polarity marking must be observed, not the location of wires.
Your air conditioner may have low voltage protection and turns off when voltage is to too low. In a camp ground, many people using air conditioners at the same time would causes the camp's AC power to drop.
If the compressor still does not turn on, check voltage to the compressor. If no voltage, trace it back to where it loses voltage. If voltage is good, the compressor would be defective. Good luck with your trouble shooting.
