bit of an odd one

freezer van... (Mercedes sprinter)

can the overnight (240v) standby be powered up while the van is in motion to provide cooling (without engine compressor - no space for one, already has aircon and extra alternator) ?

or will the bumps/vibration kill the 240v compressor?

electric 12v systems are priced really high

could buy a 12v compressor, but might as well use the mains one when it's there
