I replaced both batteries in the 5th wheel and when finished, I only get 12 volt power if plugged into 120AC. If unplugged, everything is dead. My owners manual says something about a "12V Manual Ove...

On your battery POS cable that comes out of the 'disconnect switch' and goes to converter is a 30A DC circuit breaker (small box with 2 studs...cable in/cable out on the studs)
It is the main cable 'protection'
Should be an 'auto reset' but can be a manual reset. If manual it will have a small button on side to reset it.
If no reset then it sounds like it has failed (should be 12V DC on both sides...check stud to ground)
Just follow battery POS cable.....should be in forward compartment close to batteries.
IF no CB then there will be a in-line fuse holder with a 30A fuse inside.
(****Could be under a protective cover/box)
And LOOKING at a fuse does NOT mean it is good..test them
Test those 'reverse polarity' fuses on the converter ---the 25A fuses
