AC size and generator size - advice please

I am in the process of a major transition of my RV lifestyle.
I will be buying an Arctic Fox 29Y. Wife insists that we have a generator to run the AC. We often camp in forest service/state park/boondock where no electricity is available. We also do camp in RV parks with full hookups.
Standard is a 13.5k BTU AC. Optional is a 15K.
I am strongly leaning toward the Champion 3400-Watt Dual Fuel RV Ready Portable Inverter Generator with Electric Start, largely for the ability to run on propane. I have figured out a way to transport it/store it, and move it around.
I will also install a Supco SPP6, Relay Start Capacitor 120-288V to assure the starting of the AC.

Will this generator and capacitor run the 15K? or should I stick with the 13.5k?

The trailer is total 30' long. Is there much of a difference inside between the 13.5k and the 15k? It seems like such a small difference, 13.5 to 15, that the coolness difference would be noticeably felt inside. What am I missing?

Finally. I am unfamiliar with the capacitor thingy. Where does that install? At the AC? Is it difficult?

Any comments/advice will be much appreciated!!!

FYI....moving FROM FW TH with 5.5k generator on board.

    The OP asked about an inverter generator to run his a/c.

    How does talking about a noisy 800w non-inverter generator help him?
