Ac..fridge...water heater
Happy 4th to All.....never tried this before.. On my 2015 228 can I run the Ac--fridge and hot water heater at the same Time or is it just to much for the system. Never used the water heater yet so I want to test it to make sure it works, it would be nice to have the fridge on but if it's hot the Ac has priority over everything. What do u think. Thanks

The more amps you draw the lower the incoming voltage will be and the harder your air conditioner has to work. Your resistive loads will also be less efficient and generate less BTU per amp used.
This means your fridge won't get as cold and the water won't get as hot.
If power is an issue (as in the summer with a 30 amp camper) either use a 50 amp spot (better wiring) or run the water heater and fridge on propane and dedicate as much power to the air conditioner as you can.

Most likely you will be over 30 amps draw when all on: AC 13 amps, fridge 5 amps, water heater 10 amps and converter 5 amps so total of 33 amps approximately...see thread below

I just thought of this. I think the water heater runs off of propane but u have to have water in it before I turn the switch on.

I have a 2015 2502KS. I run all 3 on occasion on a 30 amp service.. I don't notice anything funny. Everything seems to work just fine. I have a 15,000 btu AC. The fridge is your standard nonresidential RV fridge runs on gas and electricity. Even still the lights don't even dim. the water is very hot!

The OP has a popup, meaning he doesn't have a standard RV fridge.
It should have a smaller 3-way fridge, so it will run on 12v DC/propane/110v AC.
If it were me, I'd run either the fridge or the WH on propane.

id be checking the voltage regularly...if you get below 110, id drop the WH. it will shorten your life span on appliances and melt down connections eventually

Ac..fridge...water heater
The water heater runs on propane,but has a switch on the inside of the camper you have to turn on to ignite it. I do watch the voltage at the surge protector

Run the fridge on propane, in my experience it works best on propane anyway. Water pump does not pull much.
