90 amps times 12 volts equals 1080 watts at maximum. That's not nearly enough even if the alternator always put out max amperage. A few lead acid batteries will put out even less amperage.
Advanced RV models have Lithium ion batteries rated at 400-800 amp-hours together with a second alternator that is dedicated to charging those batteries. That system or a substantial generator are the only ways that I know of to power an AC while underway.
