I had a problem with one of my units and my regular AC repairman repaired it.  We took the unit out and loaded on his truck and he took it to his shop.  Brought it back the next day repaired.  Each unit has two compressor which amounts to 4 roof ACs.  Only one compressor comes on as long as the inside coach temp. is within 2 degrees of what you have the thermostat set at.  When it gets above the 2 degrees both compressor of that unit will come on until its back down to within the 2 degree mark.  I have had no problem with not being able to cool my coach in the hottest of weather.  But I don't have two big hot Boxer dogs, as Bill has, to heat up my coach.
