Does the Intelligec do "load shedding"? If so, go ahead and use both air conditioners, but DO monitor the voltage and manually shut down one air conditioner if voltage sags below 107.
Does the Intelligec allow you to preset incoming amps? I do this using my Magnum hybrid inverter charger, so on a 15 amp shore power I "dial it down" to 12 amps. On 30 amps shore power, I dial to 24 amps, and on 50 amp shore power, I dial to 30 amps.
If there is a 50 amp outlet, get a 50 to 30 adapter and use that for the shore power. Since a 50 amp can be run flat out at 40 amps, that leaves more for your RV to work with, and voltage drop may be less (I still often use my autoformer).
