2 AC's and 30 amps

I have a 321RSTS with the 2nd AC option and I know you can't run both when at a 30 amp site. So is it best to run the main AC during the day then switch to the bedroom at night? Both units are hooked into the ducting but the main doesn't blow much air in the bedroom. Also is it OK to run the main AC and run just the fan on the bedroom unit? When I do that it blows more cold air in the bedroom.

One of the vents in the bedroom doesn't blow much no matter what unit or both are running. Anyone else have this problem?

We just alternate them during the day. At night only the downstairs unit is on to keep it quiet upstairs.

I think you can buy a cheater cord that your 30 will plug into and it will plug into the 30 and the 110 to help out.

I'm with Norty. Use the main during the day and if the bedroom is too warm when you retire for the day, shut off the main and turn on the Bedroom.

That does nothing to allow you to run the second AC.. it will help if you want to use a space heater or other appliance.

I assume you typically use a 50 amp hook up. When plugged into a 30 amp outlet you have only 30% of the electric you have available with your 50 amp hook up, 3600 watts compared to 12000 watts.
Not only will not both AC run, but you may run into other issues,,, hot water, appliances etc . I would make sure you put your hot water on propane rather than electric and be wary when using the MW, coffee pot or other heat producing appliances. Good Luck.

It's a scenario that you learn to live with by adapting. Other wise you are looking for and resetting breakers.

Maybe I'm confused how they are wired. I would assume a A/Cs draws as much as a space heater or another appliance. I have a buddy that uses hes cheater cord all the time to gain extra amps from the box. If could attach pictures to this site, I would show you one. Anyone know how to attach pictures.

We have all been there. There is no way to make 30a more than 30a. There are loads of rube Goldberg work arounds, but 30a is 30a.

Adapter

What Chris is talking about is the ability to use the 30A outlet and a 20A outlet on a campsite post. Camco makes an adapter to do this. It will supposedly give you the ability to pull more amps. IMO I don't think I would bother. I would be concerned about how the distribution is done at the power station.
Let's say 1 A/C unit is pulling on the 30A feed and the other is pulling on the 20A feed. Depending on your A/C unit and what else may be on that leg you may still pop the 20A breaker.
