RV A/C in Arizona summer heat?
We may be moving to Wickenburg, AZ this summer. It is a bit cooler than Phoenix but still scorching for a Colorado boy. At some point us and the cats and dogs will have to try to survive for a few day...

One thing that you need to do is maintain the fan at full speed and regulate the thermostat, we learnt that one night when wife asked if we could reduce the fan noise, I turned the fan speed down and went to bed.
Arround 03:30 the A/C shut down, outside temp was 92, I took the filter cover off on the Dometic and discovered that the evaporator was frozen, fast thinking used wifes hair dryer since it was a very thin accumulation of ice on the fins to melt the ice, checked brakers and all was O.K. turned A/C back on and from then on regulated temperature only and maintained the fan on full speed, talking to other guests they confirmed the fact that A/C units do freeze up when the monsoon hits in Arizona.
Depending on the temperature you might have to run the A/C at night also, another thing that we have done is use the cloth that the greenhouse growers use, sold at Home Despot at the gardening shop to cover the rear window, the ladder sits there and helps as a tie down, also try to shield the refrigerator from direct sun, and if posible install a small computer type fan, we have one that runs on 110 Vac, one runs on 12 V dc and one that is solar powered, place the fan at the top it is better that down near the heater, I turn the fans on depending on what we need and where we are, this keeps the refigerator at a beter temperature than the house unit.
