Older Campgrounds w/o 50A Service

Good points on the EMS if you have one. I have one but personally I prefer to manage the power myself. I've had my system shed the television and the outlet my coffee maker was plugged into; really annoying.

If you're really concerned, have the rear air put on it's own plug like you had before. If, like you said, you go to places that only have 15-20amp service, you can then plug the front one in during the day and the rear one in at night. If your "new" unit has an EMS that will probably be all you'll need. If this is a new unit, as opposed to "new to you" it just may have one. You'll have to ask...

That's a lot of "IF"s....:E......Dennis

I have Energy Management system. When running 30 I can use both a/c. When I turn micro on, the system will shed first the water heater, then the fridge, then if necessary the rear compressor will shut down, this all depends on how many amps I am drawing. Usually it will start shedding around 32 amps. all will come back on line when amps fall back to 30 or less.

You should be able to run two ACs if you turn off water heater and put refrigerator on propane.

A NEW motorhome MIGHT have an energy management system, which will help balance the usage of available power. You most likely will not be able to run two AC units at once, but pretty much anything else will be handled by the EMS.

The adapters (50 amp splitters,NOT the 50 to 30 dogbone) are great, except for one thing. A LOT of people do not know about the Neutral and HOT on a receptacle. They think you can wire them to either spade terminal (30 or 15 receptacle). IF they reverse the 2 wires (reverse polarity), THAT receptacle will still function for current, BUT, IF you use a 50 amp splitter, THAT will introduce 220 to the RV IF either one of those receptacles have reverse polarity. It is ALWAYS a good idea to test the CG receptacles (30 and 15) for correct polarity before you connect your RV. Doug

REMEMBER, YOU ARE NOT GETTING 50 AMP SERVICE WITH A 50 AMP SPLITTER. YOU ARE GETTING A TOTAL OF CHEATED 50 AMP. 50 AMP SERVICE IS REALLY 100 AMP SERVICE.

I use a 50 to 30 adapter at sites without 50. I cannot run both ac's on a 30 amp site. I run which ever is more convenient, i.e. if we're watching TV in the front, I run the rear ac and at night in bed, I run the front ac.

My experience with 30 amp sites is that I have to manage the power. I can't run an ac as well as the coffee maker, microwave and ceramic heater all at the same time. I usually have to turn a couple things off.

At home I use a 50 to 30 to 15 adapter and it just gives me enough power to keep the fridge running and keep the batteries topped up. I can also have the TV on.

Getting ready to pull the trigger and purchase new MH with 50 amp service. We usually stay in older state park campgrounds that only have 30 and 15 amp service. My current MH has 30 amp plug and prior owner added rear air conditioner that has its own 30 amp plug so it was easy to use an adaptor on one and be able to run both ac's.

Question is how are those of you with 50 amp rigs plugging in? Adaptor to 30 amp? If so doesn't seem like you would be able to run both ac's. Have looked at 50 amp splitters but not sure if that will solve my issue? Thought about having dealer put that rear AC on its own plug before taking delivery. Living in the South being able to run both ac's is a must.

Thanks for any advice
