Very warm and very cold temps do strange and bad things to a coach. Consider doing nothing until the temps return to 95 F or less. I suggest this recognizing the coach should work in the environment you described. For me it comes down to knowing what to expect from my coach and if it is reasonable, leave it alone. One can spend a lot of time and $s trying to make a coach run as close to perfect as possible.
An example is my Cummins ISC does not like to climb hills when the temp is >100 F. I could spend time and $s cleaning the radiator and engine, replacing the coolant (ahead of schedule) and heaven know what else. However, I get in the truck lane gear down to keep the RPM at 2000 and be patient.
