AC Struggling in 90 degree heat

Is it normal for a 2019 Forest River Tracer to not maintain 74 degrees as set on thermostat. Yesterday during heat of the Day
Temps rose to 85F +??

I the late afternoon it cools down to low 80fs and at nite it actually cycles off.

Measure the temperature of the return air at the A/C unit and the temperature at the discharge of one of the air registers. There should be about a 15 degree temperature difference if the A/C is working correctly.

Not maintaining interior temps can be due to an A/C not working correctly, but it can also be caused an A/C not big enough to handle the hot outside air temps. The above test can determine if the A/C is doing all it can do and is working properly.

Adding reflective films to windows can help a lot.

Did you ask this question on the Forest River Forum? Might be other issues that Thor owners arenít aware of.
