[A/S] Bought a '72 27 ft Intl Overlander

["lml906" <lml906@xxxxxxxxx>]

I bought a 1972 27 ft Overlander.
Where do I plug it in?
 
Do I use a double-plugged 120 volt cord? 

There is a covered "BELL" brand Duplex Receptacle on the exterior 
adjacent to the access doors but nowhere do I find a 120 volt male 
plug neither mounted without a cord nor a loose cord with a plug on 
it.

There is a grey standard plug plugged into a duplex receptacle box 
inside the access door but this appears to power the exterior 
mounted "Bell" covered receptacle.



It does not look customized.
