Questions:
- What was the starting interior temperature?
- Was it consistently sunny, cloudy, shady?
- Details of the rig: 28ft Class C from the signature but how many slides? Were you keeping the door consistently closed? Any out of the ordinary insulation?
If you started with the interior temperature equal to the exterior ambient temp, these results aren't surprising. Even though it's cooler outside early, you not only have to cool the air inside but also the solid objects in the camper. Later cycles, the interior is already cooled, so you are only fighting the solar gain. Plus, since you are raising the thermostat setting, it's keeping the temperature differential limited.
This is a friend's rv--a fifth wheel cougar 33 feet.
Starting temperature was 69 f (20.6) as specified in the original post.
5th wheel partly in shade
one slide as specified in original post
doors closed for entire test
no extra insulation as far as known
It is much warmer ambient today but I was not in the 5th to take measurements.
At 5:44 pm local time ambient is 92 f (33.3 c), high for day was 97 f (36.1 c). Interior of RV is 73.
No cycling at this time.
