Joe,

I have done what you are proposing on my rig. My rear a/c has soft start and the bedroom a/c does not. I can start my front a/c on 30 amp or my gennies and once it is running I can start the rear a/c with soft start.

Once the rig cools I can turn the bedroom a/c off and only use the rear a/c. If I need to restart the bedroom a/c, I turn the rear a/c off first.

Not the perfect solution but it has worked for me. The soft start will also allow me to run only one of my 2000 watt Honda gennies and run the rear a/c only.

We have soft start on both AC’s. Can run one on a 15 amp cord, which makes it nice mooch docking. We run both an hour before we arrive off our 3000 watt inverter and makes a huge difference when we arrive on a hot day.

bshgto where did you get the control board? The hundreds of dollars they want for the soft start seems like a ripoff for the few times I am on a 30A site, so I have never pulled the trigger on it. I would consider a less expensive option though...

Check your air conditioners. Both mine came with soft starts already installed. Plus the RV tech who assists me confirmed the soft starts. Also, he sells them for about $50. Check around & don't throw away your money.

What's the best way to determine if you have soft starts already installed?

Not sure about this but I think maybe they came on the 2021 and newer models. Someone will know for sure.

Your 2018 would not have a soft start unless the previous owner installed them. If you are original owner - then you do not have soft starts.

Put a soft start on each unit, and find a way to start them up individually, I think there are special switches that do that or some kind of fancy transfer switch. Do NOT expect to use any hi amp device as well like micro wave, toaster, coffee pot, kettle etc.

I bought mine 3 years ago . There was an option on there WEB site that you could by just the control board for you to add an enclosed box of some kind and the wiring to the A/C wiring. Came with instructions and was very simple to put the control board in one of my wife`s Tupperware containers and add the wiring for 150.00 less each so I bought 2 and added them to the camper. Maybe they don`t have that option anymore. I did buy their remote controlled thermostats to. They are very salty but work as described. This is a bonus if you have pets and need to monitor the camper temps while you are away for a day trip. At the time I had 2 2000 wat gens and I could start both A/C`s ( but run nothing else ) got tired of that and went to 2 4500 watt gens paralleled in the back of the truck so I really don`t need them anymore. I`d buy them any way remember if you change campers you a can take them off and put them on the new unit. And when your done you could sell them in a heart beat on the forum board and get at least 1/2 your money back.
As for $50.00 soft starts..... not happening he is talking about your garden variety hard start capacitors form an A/C supply store That aren`t going to work for this application.

I did both AC with soft start. I can run both on a 30A easily.

I have two Soft Starts all ready to install, but got caught in our first snow storm. Now waiting for everything to melt and get warm enough to install. Also looks like I’ve missed getting my cover on this year due to the wait. I’ll be all ready for spring camping though.

How do you guys run both ACs on 30 amp? When really hot (>95 or 100), my main AC uses 16-17 amp. And I think the bedroom uses 14 or 15. Any other minor thing running pushes to over 30 amp. ??????????????????

Our bedroom (rear b/r) has the a/c with heat pump also. When at our s&b during the summer I can run that a/c from a 20a outlet in the garage. Haven't tried to run anything else as I assume it would overload the breaker. But I wonder if that unit came with soft start.
Any thoughts?

I have always run one AC on 20A, it probably does not have softstart. I put soft start on both our AC's just in case even though I have less than a few hours on the bedroom AC.

I also have the Micro-Air soft start on both AC's and the EasyTouch thermostat. Trivial install for both.
