We are thinking about installing an Auto Transfer Switch in our unit. I cannot find any info about how to wire one in. I want to know what wires I will have to redo. Does anyone have any info about wiring one in from start.

Here's a writeup on how to install a 30amp transfer switch. I've used this one and it works well. Transfer Switch

Depends on what function you're trying to accomplish.

While you are in the process of installing the transfer switch, I would recommend installing an onboard (permanent) surge suppressor at the same time to protect it and the RV. Everyone has different opinions, but I would place the surge suppressor ahead of the transfer switch. Most genny's already have quite a bit of surge/spike and frequency regulation/protection. Auto transfer switches aren't cheap and by placing the surge protector ahead, it will protect it. Look at Progressive's surge protectors.

OnaQuest thanks for the info. It looks very straight forward.
I have a Class C with 30 amp service. What I want to do is stop the pluging into the outlet for the generator or the service. I want to be able to just hit the start on my Generator when the shore power goes off. Have had that happen a couple of times this trip. It is a pain to go out and plug into the generator outlet.
Thanks again for the info.

Two input, one output. Instructions should be included.
Is this 15 amp, 30 amp or 50 amp?
Power cord and generator as input? Or is this an inverter install?
How do you transfer power manually?

I do understand that this will take significant wiring changes and am looking at what it will entail.
We would only fire up the genset if it was appropriate.
There is not room in the shore power cord storage area to install anything so I will have to move this to another area. I already have a surge protector and will install it in the correct position.

Not to be a kill joy
But this going to entail significant wiring change

And You must decide which one has the over ride function and will control the transfer switch shore or genset ( i would go with genset to power the transfer switch, default to shore on the normally closed side )

When did/does the power go out ?
And for how long ?
What will specifically need generator power for, when the shore power goes off ?

Other campers will not be happy to hear you fire up your genset at midnight to run an electric heater

For tv and lights i would stick with an inverter and 12v

Ifs its for the MW at supper time moving the plug is not that big a nuisance
Compared to rewiring your input power

Its obvious your shore cord storage area has the plug for the genset
Is there room in there for you to install the transfer switch and cut the shore cord and reconnect & make all the new connections
