I take it that you don't boondock much, so your concerns are charging while driving, and the little fridge running concurrently. Then when you get to your destination, you plug into shore power, and the little fridge runs on 120v. You somehow switch the little fridge from the inverter to shore power.
I think you just need a 2 battery bank, connected together like any other RV. They can be 2 x 12v or 2 x 6v, doesn't really matter.
While driving, the little fridge may pull more current than your truck can provide, but as you said, it doesn't run all the time. Probably runs less than half time would be my guess, but of course your truck will be charging 100 percent of the time you are driving (you will lose some when you stop for gas/food). A bank of 2 batteries should handle that great, concurrent with the truck output.
Also, all inverters that I am aware of will auto-shutdown when voltage gets low. Not good for the batteries to let that happen, but at least they won't be stone dead. I don't think that is any issue though. At the current draw you've described, that won't ever happen while on the road.
Obviously, if you do boondock, you will have to remember to unplug that fridge.
