Welcome to the forum. Your question has been addressed before, so you might want to do a search.
It depends on the power service in your coach. If you have 30 amp service (three prong plug) you will need to run your AC units separately. If you have 50 amp service (four prong plug) you should be able to run both AC units simultaneously.
We often close the bedroom door and run the forward AC unit to cool off the salon; then in the evening, we switch and run the bedroom AC with the door open. It still cools the salon some, but it gets the bedroom nice and cool for bedtime.
I imagine you want both going right now, given the weather you folks are having. Good luck and happy travels.

You really don't give enough information for a good answer.........
Is your RV one with a 30A power cord? Are there wires inside of the RV ceiling/roof to supply power to a second air conditioner? Is there a place in your 120V power distribution box for another circuit breaker and the needed wiring?
If your RV has a 50A power cord then it is also probably wired for a second air conditioner and all that would be needed is to install one and probably to put in the circuit breaker for the second air conditioner. If your RV has only a 30A power cord, then it probably does not have any provision for the second air conditioner, but it could be there. If you do put a second air conditioner into a 30A RV, you can run two of them at one time from the 30A cord, but you will not be able to run much else at the same time.
A typical RV air conditioner draws about 12/13A when running. That means that it is drawing 26A of the 30A that are available. Some newer units are more efficient and draw as little as 8A s that would probably work.
The biggest challenge to putting in a second air conditioner would come if your RV is not pre-wired for one. It is pretty much impossible to run wire through the walls and roof of a modern RV. You would need to hide them somewhere and if you add a second power cord you would also need a second power distribution box for the circuit breaker for the new air conditioner.

If you think you can depend on a 20A service at almost anywhere you camp then just re-wire the second air conditioner to an outside 20AMP connector/cable to plug into the camp site 20A pedestal circuit.
I do this all the time with my POPUP but it is easy to gain access to the inside of my POPUP. I mostly do it for an extra electric heater or heated blankets etc... The pedestal 20AMP service is on its own circuit breaker so doesn't trip the 30AMP service circuit breaker on us...
We also use the site 20AMP service for any of the outdoor activities such as fans, exterior lighting, coffee pot, electric skillet etc... Just run extension cords from the pedestal..

Yes, if you have a 30 amp RV you can purchase a dual power adapter which basically isolates the rear ac and provides a way for you to plug it in with it's own 20amp power cord. Even though I have a 50 amp rv, I put one in so when I camp at my favorite place this summer which only as 30/20 at the pedestal, I can power up both my ac units.

First off I like to thank everyone one who responded . Your input has been most helpful.
Here is more info on my 1986 Chevy chassis Winnebago Elandan . The rear b/r ac is wired it has it's own 20amp breaker mounted beside the main panel.There is also a switch that is marked for front ac and rear ac. Switch must be set to front to run front and rear at the same time. The rv is on a 30amp system. When running on 110 volts this doesn't happen,but when on my 6.5 generator it does. My question to you all is, what's the best route to go to get both units operating at the same time when not on the generator? Thank you all again for your previous input--- Clay

Quick note: I just discovered that both ac's are on the same breaker in the main panel . With either unit running, when I trip the breaker in the separate panel marked for the rear ac nothing turns off. ?
