Question about air conditioning

If you are turning on your air conditioner at the end of the day, or after traveling in the heat all day, those air conditioners have a hard time actually "cooling" things down. Seems they never catch up. I think that's because the walls, the furniture, the floor, your carpeting, your mattress, bed-linens, cabinets, everything retain the heat and it keep pumping heat until things begin to cool down outside. This seems to just be the nature of the beast.

You really have to start the air conditioner in the morning when the camper itself is cool (especially if you are in a hot climate.) Then it will keep up and actually, can potentially, freeze you out!
