I don't know how long your rig is but, my 24' unit stays more than cool enough with the dash A/C since it's far more powerful than the rooftop unit.
It's nice not having to hear the noise or burn the extra gas running the rooftop unit for nothing.
The same with our 24 foot Class C. The Ford cab air conditioning system has been superb. We rarely need it turned up to full power for very long to get and keep both the cab and back coach area comfortable when traveling in extreme heat.
Sometimes when returning to the RV after it has been drycamp parked in the sun in warmer weather and we aren't going to drive it at that time, for a short while we will idle the main engine and run the cab air on full power plus use the built-in generator to run the coach air on full power .... for a fast coach cool down when getting ready to eat, nap, or otherwise relax in comfortable temperatures.
