Generally you need to park in the shade and/or add a second A/C unit. I would skip the portable except as a last resort.
Although do check the evaporator for ice when it seems to be blowing warm air. If you have a wall thermostat you should see a freeze sensor... make sure it is placed right on the evaporator. These freeze sensors are notorious for being improperly installed or to fall away from the right position. Also check the lower plenum divider is properly positioned and sealed to separate the air in vs air out. This can all be checked by removing the lower trim pieces inside the RV.
You should allow the air to run continuous 24/7 in these conditions. It is just a machine, it does not get tired or need a nap.
