[VAC] AC/DC question

[Rob Super <rms@xxxxxxxxxx>]

I hath this question, which is purely academic at this point (i.e., I've 
not had a problem):

The chassis is part of the DC circuit (path back to battery). The chassis 
is also part of the AC circuit in that the ground wires are connected to 
it. (When connected to shore power ground is also connected through the 
umbilical to the utility's grounded outlet; if running on an inverter the 
chassis is the only AC ground.) Right so far?

Question is: if there were an AC problem such that hot went to ground, 
could there be damage to 12v. DC components as 120v. went  momentarily 
(until something tripped) to the chassis?
