During Jim Bounds tech session on generators, something he said
worried me. Apparently, due to the way that the Royale is wired with
two circuits, only one roof air is powered by the generator, and if I
want both running I need to be plugged into shore power?
Or did I badly misunderstand (which is quite likely, actually). :)

You are correct. Coachmen only used a 30 amp cord and breakers in their GMC conversion (Royale and Birch haven. )
So the din not connect two air conditioners to that power source because if both were to start at the same time it would exceed 30 amps.
They provided a separate cord for the second air conditioner so you would have to plug that into a separate receptacle.
The 6000 watt Onan can easily handle two air conditioners but your breaker box cannot. You could modify things so that you could plug the second A/C into the Onan output but Coachmen did not do that.

Oh! So all I have to do is learn a bit of residential wiring and redo
the breaker panel. Cool, I can do that! :)

Or, add another receptacle in parallel with the wires coming from the output of the Onan and leave your breaker box as is. This would allow you to plug in the air conditioner when you are running the Onan. You would want to protect that circuit with a circuit breaker or fuse.

Robin,
In my Royale, I pulled that breaker box out and put in an 8 circuit breaker
box from Home Depot. At the same time, I put in a transfer switch that
would automatically switch between the shore and generator power. With
the additional 120v breakers, I ran some new wires to put the fridge and
microwave on their own circuits and tied the second A/C into the breaker
box; I later removed the second A/C since I didn't need two A/C's on my
coach (I don't travel in the summer heat). My coach is the rear twin beds
setup and the new breaker box, along with the Statpower 40, the transfer
switch, and the junction box for the 12v system, are all between the beds
at the rear of the coach. By the way, that breaker box and two other boxes
(pulled from other Coachman units) are available for free to anyone that
wants them; just pay shipping. HTH.

I can never reply to questions about Royales since mine was so heavily worked over by the POs that it's not much like it was out of the factory. In mine, there's a new residential-style (though smaller) breaker box under the hinged bed platform in the back. It's wired to my 6500 watt Onan, which will easily run both rooftop A/C units (a really good thing when you're trying to cool the interior down on an Arizona summer day).
I've never worried about an auto-switch since the generator output is wired into a female 50A receptacle in the generator compartment. This (to me, at least) is the preferable set-up since there's less to go wrong, and there's never any reason I can think of to need to switch over to generator while plugged into shore power anyway, unless the shore power fails that is. It also gives me a handy place to put the shore power connector to keep it safe (and of course, hooked up to the generator).

I have a 76 RB Royale that had the electric distribution box completely disassembled and no buss bar. The PO had tried to run two A/C on the 30 amp box. I am in process of installing an all new 50 amp system, 55 amp converter and switcher. Not to difficult but a little costly. I need to run two A/C and other electric.
Send me a PM for more details if interested.

Or hunt down a used box and 4 prong 14-50 cord from a GM upfit coach. Should be pretty easy to install. You want to try to bālance the load as much as possible for when on shore power. That means one AC on each leg (phase) and then say microwave opposite waterheater. Then if you can split front and rear outlets to opposite legs, if you run 2 elec heaters that will balance. When pluged to the gen 14-50 receptical both legs recieve same single feed from gen as there is a jumper wire applying power to both sides of the 14-50R. Then just carry a TT-30P to 14-50R 1' addaptor in case the park has no availabe 14-50 .

JimB made a post about the split system in my Royale on the Pose on March 8th.
"note the 2 (countm) Dometic generators in the hole Always one of the first questions when we speak of generators is "will it slide out?" Yep they do. Now you may say "why 2 of'm". This is a new "minimalist" concept. One of these units is enough to run 1 roof AC and a power converter, RC has 2 pinguin roof AC units and though the Royals did not come with a "split box" AC breaker system like the standard GM floorplan coaches had, we converted him to a split box configuration where each generator will run a leg. So RC will be able to run 1 or even both roof AC units going down the road."
