House Batteries not working?

Relatively new to RV'ng, and still getting to know how everything fits together. The way I understand it, I should be able to walk into my RV, and even though I'm not on shore power, and the gen set is not running, I should be able to flick on the lights, or turn on the fans. Well, that doesn't happen. If I plug in, or turn on the Genset, everything works. I thought maybe my batteries were bad, so now I have two brand new deep cycle batteries, and the only thing that works is the step at the door when I open and close the door. Could my converter be bad? Doesn't the converter convert AC to DC? I'm pretty sure it all worked ok when I first bought the rig, but I've never completely boon docked before. Nay help would be greatly appreciated.
Thanks,

Not sure what type of RV you have, but I going to say a CLASS C. You should have two Batteries One 12V HOUSE and another 12V Vehicle. And somewhere a shout off. When just one of the Batteries drops below 10-AMPS more than two times you will need to replace the Battery as it will never return to a full charge. Now you should look for a red SHOUT OFF which kills everything in the HOUSE, the Step work only off the Vehicle Battery. Because with the HOUSE off you can still drive and operate the vehicle part f the Motorhome. Now if you turn the red shout off to ON everything on the house side should come on. Now you can PLUG into shore POWER as this will charge the batteries as well as work the HOUSE. TRUST ME THIS IS BASIC 101. You need an AMP metter to piratically check batteries.
