No power to the front of a 2003 newmar dutch star.

Hopefully I'm posting this in the right place.

Went to start my motorhome last friday for us to go away for a few days and when I turn the key on nothing lights up on the dash, the leveling panel also doesn't come on and the generator doesn't start from the panel inside or at the generator. Everything was working on saturday when I started it and moved it, I did disconnect the batteries and cleaned the cables but I've doubled and tripled checked that everything is hooked back up and hooked up correctly.

I don't even see any power coming to the dis-connect switch, both batteries are showing 12v, I don't know where to check next.
