If that's all you're running, you should have plenty.
4 GC batteries should get you about 410 amp-hours. The LED lights draw next to nothing, so unless you have them all on and leave them all on all night, it's not even worth calculating.
For the fridge, it will depend a bit on the outside temperature but a full size Norcold draws about 12 amps on D.C. If it was running continuously, that would be about 33 hours on your batteries. If you're not constantly opening the fridge then it should not be running constantly. Overnight, from say 10PM till 8AM, it would probably drain less than 60 amp-hours out of your 410 amp-hour supply.
You can even make it run less though if, while on generator or when the engines are running, you set the fridge thermostat to 'max', then set back to normal temp before you go to bed.

I have 4 GC batteries as my house setup. I have sat on the hook for close to 2 days without running my genny. That includes running my fridge and lighting (LED), and using my LED TV in the evening. I installed a victron energy monitor on that bank and it is a great resource for keeping track of the amp hours used.

I was looking at the Victron also versus the other big name. Was the Victron easy to hook up?

It was very easy to set up. The connection from the monitor to the shunt uses phone jack type connector. After that you just enter in the amp hour rating of the battery bank and you are off. I have had it in the boat for two seasons now with no issues.
