Having a LOT of experience at this I respectfully disagree.
The dash A/C on a Ford E series chassis is FAR more powerful than the rooftop unit is, it’s serious shortcoming though is its fan. It’s easy to overcome this though, set the dash A/C to point straight down the back, NOT on Max A/C, and open the rearmost roof vent (bathroom in my case) wide open, the vacuum created will pull the hot air off the ceiling and pull cool air back there to replace it.
I did this just yesterday while using my C as a base camp while SeaDoo’ing with some friends. The dash A/C alone was able to keep the entire coach around 77 F while it was 95 F, 110 F with the humidex, outside.
I didn’t start the genset till I got to the lake and parked, then shut it off for the trip home.
