Swap 12v for 120v Fridge Element? UPDATE 2
EDIT--it turned out you can't swap them--they are not the same and it would fry things if you applied 120v to the 12v element ---------------------- UPDATE 25 Jan--12v is cooling down the freezer....

12v element wattages:
On battery 12.8v/9.5a = 121.6w
On converter at 13.6v = 135.2w
On converter at 14.8v = 172.6w
Note the manual's example of 14v and 16a = 224w, so the element can do more than what I am seeing. I haven't looked at the voltage at the fridge to see if much voltage drop. Have to check that out.
So now trying the long test again to first get the fridge down to proper cold temps on gas, and then to maintain that with 12v at 13.6v on converter.
If doing this for a long period and you don't want to float the battery bank at 14.8v, then 13.6 it is. If you did need a higher 12v voltage, then you would need a second converter just on the fridge.
