   Agreed, which is why I was considering putting one of my   
   marine shore power connectors on the house tied to a 220v   
   line breakered for 50a service, which is about the max the   
   truck draws, or drew when the recorders inside were analog,   
   which included hvac system running full tilt.  Instead,   
   often when working on things in the truck I was having to do the heavy   
   extension cable off a 120vac 30a circuit and still having to be concerned   
   about what all I operated from it.   
   At least I could get the audio gear up and cranked on that,   
   or power tools if needed, but no hvac, etc.   
      
   Regards,
