Start delay on Dometic air conditioner

My coach has two Dometic AC units and a 6,000 watt Onan quiet diesel genset. If both units are enabled when the generator is started they both hit the generator at the same time which overloads it and forces it off line and the cycle repeats every time the generator resets.

Does anyone know how to change the delay in one of the AC units so that the generator has time to recover from the first one before the second one hits it with a starting load?

I have not a clue what you have, what year, an EMS or not, or much else, but we have no problem with this in our old 30amp coach, even if we're not plugging in our rear air separately at the shore pedestal.
As for a stupid transfer sw. that could fail, we have not and plug into the genset outlet when storing the cord away, right next to it. I mean how difficult is this for a no brainer in coach engineering. Maybe I'm just missing something here.
As for your original question, I'd probably break the circuit on the rear air and install a time delay on pickup relay in the circuit.
