Yeup!

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,
