Is the gas portion of your refrigerator broken? If so, I'd advise 
getting it fixed. Since the refrigerator works on electric, it should be 
a fairly simple fix to the gas burner portion.

As to your inverter question, I don't think this is practical.

You're going to need a lot larger inverter than a 300 watt unit for 
continuous duty. Inverters are inefficient, so you'll need to figure on 
probably in the neighborhood of 600 watts draw from the 12 volt 
circuits. That's about 50 amps. You'll stress the charging connection in 
your trailer plug with this high current draw, and may run out of tow 
vehicle alternator charging output, risking discharging that battery 
too. Not to mention that a 600 watt inverter will be fairly expensive.

I'd try to get the gas portion of the refrigerator going.
