If your transfer switch is readily accessible, you might try connecting your shore power cord wires directly to the wires going to the distribution panel using wire nuts. The using portable genset see what happens.
By doing this to take the transfer switch out of the equation.

“Unfortunately, I’m guessing I’m down to eliminating components at this point.”

Since it happens with either genny I would doubt it’s the shore power cord. Do not dismiss connections at the main panel and the possibility of a defective main breaker...

Ok. That’s what my post was originally about. I asked how the wiring went coming into an RV typically. . Main panel? I just have power coming into a circuit breaker panel. That panel has a main breaker which may or may not be bad.

I tightened and checked every AC connection on the panel. And on the ATS.

Everything looks like it wires directly to the ATS first. No main panel. Just the one panel.

I’m down to isolating components and the ATS is the first one I need to do.

HadEnough,

Particularly if the transfer switch has been cycled when under large loads.

I was able to get 1/2 or 1/4 turn on a couple neutrals and hots in the circuit branches.

All wires to and from the ATS were securely connected inside.

I thought you might find some heat discoloration while tightening these various connections.

Intermittent problems can be challenging. How long do these episodes last?

I've never seen that type of problem with a breaker. I've seen breakers that would not reset, And once seen one that would not carry the load it was rated for. I've also seen where they were turn on and off every day switching lights in a commercial/factory work/wear loose and heat up.
Stop up my way and I'll take a look at it.

I only mentioned the breaker since it is a mechanical-magnetic device - the ATS could still be suspect, whether the contacts, coil or faulty logic board...Bypassing is the ticket!

HadEnough is doing some mighty fine sleuth work!!

I find it odd to be the transfer switch since both the utility cord and on-board generator have the same issue.

Maybe start with isolating some circuits like setting the fridge and water heater to propane only.

Most transfer switches only uses logic on the auxiliary power supply. The OP uses shore power to feed rig from portable gensets. Transfer switch logic would also not cause brown out type issue. only thing in transfer switch that could cause problem is contacts.

Way ahead of you. Being off grid/boondocking, it’s always all set to propane.

Generators only come on when we need to microwave or use air conditioning. The rest is propane and solar.

This little tidbit is just the kind of stuff I was hoping to learn on this thread. Thank you.

That was actually my first guess. The contacts.
