Greetings;
My neighbor's RV (Class B-Mallard) is an older model with two Air Conditioner on top. According to her, there's a problem with the electric breaker which need to be reset constantly! Does someone know what maybe the source of the problem?? Any and all suggestions are welcome. Tkx. in advance - BB
p.s. Sorry I don't know the make or model of her A/C's

There could be several reasons for the breaker tripping.
1. Power cord from shore power undersized, to small to handle the amperage of the AC.
2. Condenser and related equipment need to be cleaned, and service.
3. The circuit breaker control the AC is weak, or a bad electrical connection.
4. The unit is self might need service. Like a bad start cap. or starter relay.
If she knows little or nothing about it, have a qualified service tech check it out. JM2Cents Bill

Good input from PN. Additional information would be very helpful. AC size, power plug size, other loads and AC voltage at the pedestal and in the rig.
If it's 2 ACs on a 30A cord then that is always iffy. Some have reported successfully running 2 ACs on 30A but consider that the ACs are probably using 22-26A. That by itself is a very heavy load. Plus refer, converter and other AC loads equals tripped breaker. What breaker is it? Pedestal, 30A main or???
Also even if the breaker itself is not the root cause it should probably be replaced after resolving the other issues.

Check that you have 112+ volts in the RV with the air running. If power is good replace the breaker. If it persists with a new breaker and good power put new air units up there. If they are 13.5 get the high efficiency models.
Assuming it is a 30 amp RV I assume she knows to not have the water heater on electric or use a microwave, hair dryer etc with both air units running.

Older air conditioners draw more power than modern models, and as they get older they may draw even more. If one or both of the compressors is beginning to fail, it'll draw a lot of power. If the condensers are dirty, that'll make the units draw more power. The condensers are the radiator-like heat exchangers on top of the unit under the plastic shroud. These must be clean all the way through. If the condenser cooling fan isn't running right, it'll also make the unit draw more.
And, as said, the circuit breaker might be getting weak. If it is the usual household type breaker, these are cheap. I'd test the total draw with an ammeter, but if you don't have one, just replace this breaker on speculation.
In addition, check all the power connections along the way...the receptacle, the plug, the power inlet at the RV, the connections in the panel, the connection of the breaker to the lug, the connections to the wiring to the ACs. All connections must be clean, dry, and tight, and the copper must by weak-coffee color, never espresso-colored (burned...and I like espresso).
