This past weekend was another typical Texas summer camping. We arrive mid afternoon and setup. As soon as possible I get the air going. The temp gets down to about 94, and the A/C breaker trips. Over the next hour, it's trips several more times. We managed to get thru the night cause it quit tripping as the night cooled a bit.
The next day I contacted Lyle's Mobile RV service. When the tech returned my call, he first questioned me about my electric water heater being on and running the AC on high instead of low. He also gave me his number in case I had more issues. It ran pretty well the rest of the weekend. He could've came out and took my money and told me the same thing. If you need a mobile service around Longview, Tx, they get my vote.
Low line voltage is a huge problem in hot weather especially during the heat of the day. By taking the HWH off of electric your line voltage probably came up several volts and lowered the current draw. A volt meter to monitor line voltage should be used by all for that reason.

If voltage with A/C running is below 110 VAC in your RV you risk damage to the A/C. You likely need to thank the breaker for saving your A/C from burning up!!!

Often I forget the draw that HW tank will take, and I get surprised when I camp in a 30A site. I just have to refresh my thinking and turn the fridge, HW to gas only and I make coffee on the stove.
Not saying your in a 30A site, but that's when it gets me.

This happened to me last year 4th of July, Texas, hotter than you know what. The campground was full and the breaker in the RV would trip. My friend in the next site had trouble with the breaker on the pedestal. What happens when voltage drops is amps go up and stuff trips. We both had 30 amp rigs. We used adaptors and switched to the 50 amp outlet and no more problems. There are alot more 30 amp rigs than 50 amp.

North American Voltage Ranges
In the US and Canada, 220 volts, 230 volts, and 240 volts are used interchangeably to describe one voltage range that is used to power larger appliances. Similarly, 110 volts, 115 volts, and 120 volts all refer to the one voltage range that is available through the common electrical outlet. The sources of these seemingly different numbers are as follows:
The 220 volt and 110 volt designations are older and familiar terminology, but are no longer used in either product design or by electric utilities in the US and Canada.
The 230 volt and 115 volt terminology comes from equipment design standards. Equipment is commonly designed to operate at 230 or 115 volts plus or minus 10%.
From this info you can see you are OK down to 105vac. Progressive Industries EMS will shut off at 104vac. As the voltage drops, current will rise, so at lower voltages it is best to run the Refer. and W/H on gas.
Hot water on the grand scale of things takes huge amounts of power. A medium sized tank water heater in a home costs approx $50-60 a month just to heat hot water.
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.
