Thanks for your response. We have been here overnight already. It does seem like the air is coming out cool. Just not cooling the unit down during the day.

Putting air pillows in any skylights, putting additional insulation on windows, especially those facing afternoon sun will all help.
Wrong. The air exiting the unit should be 18 to 20 degF lower than the air entering the unit. DO NOT use an infrared(laser) temp gun for air temperature. It will only measure solid surface temperatures.
With a hot RV, it may take overnight to get it completely cooled down. DO you have two 15,000 BTUH units or two 13,500 BTUH units? The A/C has to cool the air down inside the RV, and also all the cabinets, walls and furniture.
Keep awnings out if not two windy an the south and west side. Keep window shades closed, put Relectix in the windows on the sunny side, park in a shade.
Take down the inside ceiling assembly and make sure that the dusts are sealed so that it is not bypassing sit internally or blowing air into the ceiling. Use the foil tape to seal up openings.
