110 shore power and generator

Is there a proper procedure going from shore power to firing up the generator? Must I unplug first before starting the generator?

Nope. There is an automatic switch that will engage the generator once it kicks its A/C on--disconnecting the coach from the A/C plug at the same time. (The generator has priority over the wall plug.)

I've run the genny before while plugged in without issue.

nope

your ATS, automatic transfer switch, handles that for you
it will default to the Generator whenever it is cranking/running
and fail back over to the Shore Power, if you are still plugged in, when the Generator stops

the ATS is what allows you to do anything, power wise, without fear of 'overlapping' of power sources, since it's job is to switch to only one.

You could have your RV engine running, the generator running, and be plugged into shore power, all at the same time - no problem. Your ATS would use your Generator's power primarily, the Shore Power secondarily, and the Alternator, otherwise.

The only thing I do when leaving a campsite is start the generator while plugged in that way if I am running the air conditioning and anything else it seems to be easier on the generator. Same when when plugging in leave the generator running until I am on shore power. Probably no real science behind it but I figure if everything is going already easier for the system to switch power sources then it is to turn everything off and then back on so everything starts the same time putting full load on whatever power source you are using

That's actually the opposite of what you should be doing. Turn off all loads before having the ATS switch sources to prevent excessive arcing on the contacts. When the ATS switches everything running will be unpowered for a split second anyway as the switch is break-before-make so any loads already running will all try to start again at the same time anyway (except for the Air Conditioner compressor, which has to time out before it restarts).

Sorry about the slow response/question but I just stumbled unto this thread and have a question.
This is the background: you have settled into your full hookup site for the night and enabled AGS. Campground loses power and eventually AGS powers up generator. Does the ATS block or prevent backfeed into the grid

The ATS is designed to work under load. There is a time delay built in to be sure one contact opens before the other closes. Generator will be up to speed before it comes on line. If power goes off in the middle of the night or when you are not there, The transfer happens all by it's self.

YES, Gen will not back feed the shore power. There is not connection to allow that to happen. It would take a catastrophic frailer for that to happen and gen breaker would surely trip if it did.
