I have a 2004 Kountry Star and while using a vacuum cleaner that was plugged into the front receptacle above the stairwell. it just stopped and I thought I tripped a breaker 1) no breakers were tripped. 2) It appears a total of 3 receptacles were affected the one in the stairwell, the one behind and above the passenger chair in the cabinets where the cable connections were and in the cabinet above the drivers seat where the forward TV plugs in. So no breakers are tripped, all other receptacles are unaffected... and the receptacles listed are not themselves bad because there is no voltage present on any wiring present.... Is there a wiring schematic for 120v wiring so I can see where the wires go to or come from.

Your rig likely has an inverter/charger that has a by-pass circuit which powers some of the plug-ins while rig is on shore power. These inverters usually have a resettable pop-out fuse on the side of the cabinet. Inverters are located in the basement or in a cabinet in the bath/bedroom area.

You've plugged into an inverted circuit and tripped either a 120 volt circuit breaker on the inverter OR the 12 volt circuit breaker in the inverters supply cable from the coach batteries.

Hopefully the inverter has not been damaged.

My inverter for the three outlets you describe , in my coach, is in the compartment behind the passenger side dual wheels .

I should have mentioned ; my coach these three outlets are the only three inverted outlets in the coach , and the 400 watt OEM installed was only for the TV , a satellite receiver ( above the passenger head ) and the outlet by the stairs. ( Lap top; cell phone charger for passenger use )

Mine was replaced by a previous owner with a 600 watt unit and doesn't charge the batteries . It is also a manual bypass model ; I have to go into the compartment and move the plug from the inverter to an outlet in the rear of the compartment if I don't want them inverted .
The 12 volt circuit breaker ( 50 amp )for the inverter supply is in the power cable bay , drivers side ; below the battery disconnect solenoid.
A large inverter/charger was an option that my coach doesn't have.

Also check for a tripped GFI outlet, most likly in the bathroom. Small appliances are known to have a small internal fault that can trip GFI's.

Yes, you maybe able to get a 120v wiring schematic from Newmar..... they sent me one last year . But, it's just sort of a guideline. The tech will do what they feel like doing when they build it. A new guy will do it differently than an experienced guy ( these are words from Newmar)

Now to your problem.... I had similar last years, hence my request for a wiring diagram. I ended up tracing the wires and found that a neutral in one of the receptacles was disconnected. So, that outlet and the other ones downstream become non-functional. RV's use a very cheesy receptacle and they are know to have the tendency to work loose. Here's what they typically use.
