If you are in Florida if you were to stay home in the MH you will quickly find out that the AC can NOT cool down the MH to a comfortable temp from the hours of 12:00 to 4:00.
You can help it by putting van windshield sun shades in ALL the windows including the windshield of the MH, draping material behind the cab seats to block out the heat from the cab entering the coach, putting RV covers in ALL the vents, and skylights. Whew! A lot to do but it DOES work to help the AC unit, if you were to stay in it all day. Which BTW you will have to do all this come Saturday and Sunday if you want to survive the heat! :B
IMHO, JMHO
SHUT THE AC OFF and open all your windows while you are at work.
Put a windshield sun shade on the MH windshield AND cover the opening between the cab and coach. Put sunshades on the side of the MH that faces the west and leave those windows open also.
After experiencing the Florida heat during summer and what these Florida CG's charge for electric and seeing what MY bill was for running the AC 24 7's....If I was working during the day, I would definitely shut it off. All the AC will do while you are at work is struggle all day to keep it someone cooler than outside.
You will be returning after the hottest part of the day so go in shut all the windows and fire up the AC it will cool down quickly.
Good Luck.
