cooling vs. heat gain
The roof air conditioner can, at best, cool the air it intakes by 20°F. During hot weather,
through the day, your RV will absorb heat, increasing the inside temperature. This is referred
to as heat gain.
To keep the inside temperature comfortable, reducing heat gain of the RV is just as import-
ant as the cooling ability of your air conditioner. To reduce heat gain, follow these steps:
1.
Park the RV in a shaded area.
2.
CLOSE the blinds or drapes.
3.
Use the awnings to shade your RV from sun exposure.
