Welcome to Florida humidity! If you leave the door open or leave a window open any length of time you have allowed the good ole Florida humidity to get in your RV and then condense on the cold white plastic cover of your A/C. Seen it a hundred times...usually folks from the north who are use to opening windows in the summer.
