there are several factors involved which include the temperature and humidity outside. If your unit is dirty (coils), it will not be able to cool as efficiently either.

Another factor is size of the unit versus the size of the area needing to be cooled.

Basically everybody's situation will be different from yours unless it is the exact same rig parked next to each other under identical conditions.

But what you describe does sound similar to a rapid cycling condition which could indicate low coolant levels. But that is just an educated guess. mid-90 degree days are hard on the system.

Keep the door between the main room and garage closed if the garage room isn't being used. That room is not insulated like the rest of the trailer.

The cycling on/off of any heater or A/C is controlled by the Thermostat, you set the temperature. If it cycles early like your experience, its most likely a safety device or faulty mech/elec. device. It needs to be checked out.

If it's a Dometic digital thermostat there is a thermostat/furnace interface program procedure in the manual. Very simple, might try that.
