My Voltage toy hauler has three a/c's and the interior temps stay in the low 80's when we're at the lakes near Phoenix during triple digits.
For your airflow problem. Our main a/c (living room/kitchen) is a fully ducted unit. I removed the main a/c and found the metal sealing tape bound up in a ball in the plenum below the a/c. Most of my cooling air was disappearing into the ceiling and not coming out of the vents. Turns out the builder tried to stick the metal tape to saw dust. Once I cleaned out the old tape and gave the area a good vacuuming and re-tapping, there was air flowing nicely out of the vents.
One other thing I found was there was little air entering from the two ceiling intakes. Turns out the flimsy intake duct was collapsing and closing off the air flow. I put in a 1" piece of 1" PVC to hold the duct open. This and re-tapping the plenum got the air flowing real well.
Another thing I did was remove all of the vent covers and re-taped the vents for good measure.
