Hi Jim,
	Most big rigs run from 220VAC if for no other reason, just load
balancing.  Big rigs will often pull more that 20 amps of AC line current on
modulation peaks.  So to prevent the line voltage from dropping anymore than
is necessary, we often put the HV power supply on a separate 110VAC side of
a 220 circuit.  And then run the rest of the rig, and other paraphernalia,
from the other side.  This is call load balancing and it reduces the current
on the common line of the 220 service and thereby reduce power voltage drops
on modulation peaks.
