Would it be possible to run a small RV refrigerator while towing the travel trailer that the refrigerator is in? My Ridgeline's alternator/7 pin connector wiring apparently can't handle it. The RV 12 volt battery drains completely on long trips. This refrigerator only pulls about 175 watts. The Ridgeline's invertor should be able to handle it. This is a Dometic refr. that can run on 12 volt, 120 volts, or propane.
