no power inside 94 mallard

The box outside near the power pole is called a "pedestal" if it sits on it's own post or a "load center" if it is attached to the shed or power pole. Just trying to clear up any confusion. A "power supply" is typically a device that has 120V input power and a reduced voltage output. In the RV world, the output of an RV power supply would be around 12 VDC.

You more than likely have a disconnect or load center near the powerpole that provides 120V electricity for an RV,i.e. something of a steel box where you plug your shore power cord into.
Yes, it has two breakers and a plug 110v

Test the outlets on that to see if you have power there. WILL DO

If so, plug in the RV cord and you should have both 120V inside and 12v to charge a battery or the lights. If not, you may have a hidden GFCI receptacle that has tripped. IT can be close to a sink in bathroom or kitchen or even outside on the RV's exterior. I'll let him know to look for a second GFCI in those places, he was very impatient last evening so may have overlooked one. the bath one was ok.
Most of the time, a travel trailer has one or maybe two 120V circuits that provide all the power to the outlets. GOOD TO KNOW
If a GFCI is tripped, you won't have any power at the receptacles.

If the GFCI is not able to be reset or tested, there is no power to it. Go back a step and check for power upstream of the GFCI, at the breaker in the trailer or at the place where you connect the shore cord. WILL DO. THX
Your issue is probably something easy, look for the most common place first.

The converter can be located in different places. It is commonly mounted in the hall way down close to the floor.
Another common place is along the side of the bed.
he found it, ours is under the bed near the lifting arm.
It should have 120 circuit breakers on one side. They should be all turned off applying light pressure toward off. Then turn main breaker on if equipped, then branch breakers one at a time.
will let him know
Next to the 120 volt circuit breakers there maybe a small plate that covers 12 volt power distribution center. The converter in your age of rig is behind the circuit breakers. THX

Sounds like some kind of jury rigged system. Normal hook up would not include any kind of external power supply. Without seeing it, it's hard to say whether he could replace it himself, or, what it is supposed to be doing. It doesn't appear to be juryrigged. just the electric pole the power company put up and the power supply that is connected to the rig itself

Is that "power supply" doing what the converter is supposed to be doing?there are two breakers on the outside powersupply and one is running the lights in the storage shed and lights the previous owner put up around the top of the shed.

Is that "power supply" plugged into a GFCI outlet? Is the outlet tripped?as far as I know it is.

Could you post a picture of it? Maybe tell us (from a label on the supply) what the input and output voltages are?sadly, no/ no camera on phone

The battery, depending on size and shape of it's storage location, would be a group 24, 27, or 31 DEEP CYCLE marine/RV, 12 volt battery. If he installs a new battery, make sure it gets connected properly (ie: positive/negative wires on the correct battery posts). Hooking it up backwards will blow some fuses.
I'll let him know

no battery, someone stole the one the previous owner had installed.

what size battery would he need to buy?

now he's saying it may be the power supply that connects the Trailer to the pwerpole is this something that he could swap out himself? or does a professional need to do it?
