Fridge 12 vt element draws about 7 amps from what I recall.

If in the alternator charging loop should easily be compensated for by the
charging.

Running lights and AC in vanagons is WAY up there with amp draw

Radiator fan, dual fans in the a/c evap, lights, radio  40 - 50 amps easily.

I suspect the batt is not in the charging circut while underway.
