AC Hard Start For Generator

I have a Champion 3100 inverter generator. It is having issues starting my Dometic 15k BTU AC about half of the time and overloads the generator.

I know the generator is a bit under powered for running that AC but was wondering if a hard start cap would help this problem since if the generator is able to start it, it runs fine?

My other question is which cap should I get? The model is Dometic B59516.XX1J0 Brisk II Black Air Conditioner (15,000 BTU 410A)

Here is the diagram (based on the manual):

3100 should run it just fine if that's running watts.
Pic of outlet your plugging into?

It has a normal 30 Amp RV plug on the generator. It is 2800 running and 3100 max.

If I can get the AC started, it works just fine when it is running but that is only about half the time. I even tested by turning off some of the breakers like only having the converter and the AC breakers on and it would still only start it about half the time. The other half the generator would overload and I would have to turn it off and back on again.

Here is a link to the generator:

I would also mention that my only testing of this was over the weekend where it was around 100 degrees the whole time.

Dometic recommends a minimum of 2500 running watts.

A hard start may or may not help but worth the try.
Spp6 is what you want.

Another trick is to add a delay relay (amazon) to the fan start. that way, all available power goes to the compressor during startup. Goes in line with one leg to the blower motor. Set it at 10-15 seconds. That said, some also have a delay off feature. That allows the motor to run a bit after the compressor shuts off, thus allowing you to get that cold air left on the coils and in the vents inside your rig.
