You could find something that would work. But your generators must be electric start. Nothing on the market will work with pull cords.
If you had a built-in generator. Then all the transfer switching is there for you already.
IF not then You can buy a transfer switch aftermarket.
You could do something with a couple of time delay relays and a shore power sense circuit to automatically start a generator. You'll have to also sense when the generator starts and not have it continously cranking the starter motor. You could sense the stator winding voltage or the voltage from the generators internal alternator to stop the start sequence.
There are a host of other considerations to make. Like low oil shutdown, Thermal overload and many, many others to ponder.
Then there is issue of when breaking down camp. Is the generator going to automatically start everytime you intentionally disconnect shore power?
Don't play with electricity it can be terminal.
You may need a licensed electrician to do this work.
Speaking of work,
I'm not a licensed electrican but here is what I was fixing last week.
A Radar modulator,
negative 120KV DC at 4amps isolated from earth.
Within this is a +32KV DC bias supply
Within this is a -1KV AC screen grid circuit
Within this is a +500V DC control grid circuit.
Plus the normal 5V 15V dc logic control circuits.
The problem was within the 1KV screen circuit and another beam switch vacuum tube.
Oh ya and this is all (except for the 120KV stuff)contained in a tank full of oil about the width of the wheel wells of our trucks.
Earth ground is at the top of an eleven foot tall vacuum tube.
What does it do. Its a fast 1000 x per second high speed switch for the 120KV DC circuit that supplies the final amplifier Klystrons.
So I know how deadly electricity can be.
I've never claimed to know more than anyone else, either.

Does this only work with Cummins/Onan (The diagram only shows their brand? Does anyone have one (what brand of generator and does it work? How long does it take for the autostart after shore power failure?
Maybe a similar product is available with other generators. I already have an expensive Honda portable setup. I have used it twice for 1 to 2 hours because of campground mishaps, but I was Home and able to setup the Hondas up and fire them up because we got some warning. I wonder if this feature is avaiable and securable for a portable setup (I doubt I'd be going anywhere during this time so the only dog needing A/C would be me) and not having to get up for this would be nice.
