2005 Diplomat - Only one A/C at a time?

[DanEllis]

Our new 2005 Monaco Diplomat has 2 A/C units front and rear and 50 amp service. According to the owner's manual I cannot use Front and Rear at the same time - I need to select one zone. Is there a way to run both A/C units simultaneously? How do I do that?

thanks

On my 2000 Diplomat you start the A/C in one zone and then switch to the other zone and turn the other A/C on. At that point, they both run.

I would have thought that, if anything, being 5 years newer, yours would be even better?

Maybe the owner's manual is saying that you can only run one AC when on 30Amp hookup?

The 30 A shore cord I got with the coach was pretty well fried at the connectors. I'm guessing someone tried to run both ACs at the same time on 30A.


Edit: I looked at the on-line 2005 Diplomat Owner's Manual and don't see any mention that only one unit can run. Page 154 describes the operation. There is a 2 minute delay for the compressor to kick in.
