Others will chime in I am sure - but for my 2 cents worth - I think you will trip the breaker and come back to a cold coach with warm refrigerators and freezers. There may be some other 120 vac loads you have not considered like the battery charger/inverter and auxiliary air pump. The AH will pull about 12 amps, leaving only 8 for all the other loads. The AQ uses 12vdc fans and pumps and the batteries will have to be charged to carry those loads.
On the 20A circuit you have only half of the split phase, so the 240 volt heater is not in play. The 12.5 amps I mentioned is the 1300 watt heater that is also installed for trying to run on 30 amp, 120VAC only. But even then, as I suggested, I don't think 20A will do the job.
