Yes, the shore power should charge the batteries. The converter is in the box that the 12v fuses are on...I pulled mine out a few weeks ago after both shore power and genny stopped charging the house batteries.
In my case, it turned out that one of the two auto-resetting circuit breakers under the fridge went bad (probably stuck due to over-current; I did something stupid, and no it wasn't accidental welding).
I just used a continuity tester to check both relays, and found the one that didn't work. The bad one was one closes to the front of the fridge:
The auto-xfer-switch is also under the fridge, just to the right of this pic. (Front of the RV is to the left in this pic.)

On your inverter, it basically has multiple "inputs" for power, and distributes accordingly? So generator and A/C plug into it, and then you just wire the "out puts" to RV converter unit and such?
no it only has one AC input, i have an auto transfer switch outside of that switches between shore/gen power.
iirc, it has one AC input and two outputs, one is just a pass thru for incoming power that goes back to the house AC breaker panel, the other is the inverted power which i fed to a new breaker box where all my inverted breakers live. so when i'm not on shore or gen power, only the inverted lines are getting power and like the fridge and A/C get no power.
also if you're on 30amps, consider moving to a 50amp set up while you're doing this. i wish i had.
"Hasn't exploded yet" is what PG&E said in the Bay Area up until 2009 when the pipe blew up and wiped 9 houses off the side of the hill. The pipe had been there since the 1940's. Oops.
On the other hand...having essentially no floor under it prolly helps a lot...even a slight breeze would diffuse the hydrogen and oxygen gases to a much lower level than needed for a problem.
While I sound like I'm telling you this is dangerous, I actually would probably do it myself, if I wasn't worried about water getting on the electronics...that's my main reason for not wanting an inverter or charge controller mounted like that.
yeah, there is ventilation on top (above the frame rails), to the right and through the bottom. plus it's rare that the batteries are really low and get an intense charge so i'm not really worried about heavy off-gassing.
as for water on the inverter i actually have a cover that goes over it, it was the original chassis batter cover. i drilled a bunch of large holes on the side of it for heat ventilation...
you can see a pic of it here...
allnight, we should meet up next time i'm in the bay area. we stay there often, we used to have a house in La Honda and all of my wife's family lives there. we usually stay at this crappy mobile park in RWC when we're in town.
