Again, without some idea of the voltage during start up it is impossible to say. Even at a campground, voltage sags in hot weather are notorious and if your compressor is already compromised, the low voltage may not be sufficient to kick it over.
The compressor rotor could also be locked. If so, you might need a replacement (might be cheaper just to buy a new one if not in warranty).
Call Dometic and see if the unit is still covered.
If not, before you buy a new one, you can try removing the fan control wire from the rear of the thermostat and see if the compressor only will run. Once the compressor rotor unlocks, it should work normally (one would hope).
