Check generator circuit breakers? If yes, it will probably be the transfer switch.

Could be the time delay in transfer switch. You can bypass it easily for temporary Genny use. Unplug from shore power, disconnect batteries, open transfer case and flick tiny dip switch to by pass. If after doing this, you have power from Genny, then you need to replace the time delay circuit board.
( because you will no longer have a delay) Its very cheap and easy to replace.

Had the same problem once. The source of my problem was the junction box where the power from the generator is connected to the power lines that goes to the transfer box. Wire nuts were used to splice the wires hot wire had worked loose. New wire nut and all was well.

Yup, Checked the generator circuit breakers also. I'm pulled in at Walmart now and it's going over 100F today. If it's the transfer switch, would I be able to get power if I pull into a RV Park and plug in ??

Check at the generator for a fuse which might have blown. My Generac has a fuse as well as a breaker.

Do you actually have a transfer switch? Some rigs don't. if not, you will have a receptacle inside where your cord is stored. Make sure the cord is plugged into that receptacle. That should give you power. Do you have power to the other 110 volt outlets in the coach with the generator running?

Bob, I don't even know what a transfer switch is ! LOL
There is NO receptacle inside where the power cord is stored.
BTW, I have a 2010 Newmar Canyon Star 3920.
I had NO power in any of the electrical outlets even though the generator was running.
I am now in an RV Park and plugged in and I have power ??

Silly question, but do you have an owners manual? I've had my unit 2 1/2 years and I'm still learning stuff after my third or fourth cover to cover reading of it...

Hey Nuge, NO silly questions when you own one of these rigs - as far as I'm concerned !! LOL

UPDATE: The local RV Service tech guy came out this afternoon - shudder to think what that's gonna cost being it's a Sunday on a Holiday weekend...
He located the 'wire' that he said is the source of the problem and said now has to follow it back to see where it is shorting out. Seeing as it's 102F here right now he suggested that I find the wiring diagram for the 'house' part of the Coach as that will help him follow it back faster. I have to bring the rig into his shop Tuesday morning where he said he will find the problem and fix it.
I've gone through (quickly) the mountain of Manuals that came with the rig. Any suggestions where I would find this wiring diagram ????

My wiring diagrams are on ledger sized paper. (Double a standard sized sheet) My M/H came with four folders full of info and I've downloaded and printed out another folders' worth since I got it!! Best guess is look for those big sheets....

You may not have the wiring diagrams - not all coaches come with them. Often you have to request them from the manufacturer. Maybe another Newmar owner could advise you on that.
He really shouldn't need a wiring diagram to find that problem - there are a very limited number of places it could be, basically generator to transfer switch and switch to the main breaker panel (load center). And since you say it works ok on shore power, that leaves only the wiring from generator to the transfer switch and the switch itself.

UPDATE TO THIS THREAD:
It was a totally fried Transfer Switch !! See pics attached (if I uploaded them right )
Terrifying to think what 'could' have happened !
Tech guy said it could have been due to overloading (certainly not by me !) or loose wires ??
