Tire pressure before going south
I am curious what others do about air pressure in your fifth-wheel tires. If you set it at proper PSI in the north at 30 degrees and then end up in FL at 90 degrees, what effect will that have on the ...

Tire manufacturers compensate for temp changes. Always set pressure in the AM and don't change it until the next morning. They may fail for some reason but it won't be from failing to compensate for ambient temps.
While that is good general advice, one also needs to be aware of unusual conditions.
Some places in the western US it is easily possible to drive in a single day where you might have a temp. span of 70 degrees or more; high in the mountains down to death valley for instance.
Under extreme conditions like that you should check and correct the pressure more often.
Not according to the tire manufacturer. I wouldn't leave WVa in 18 degree weather, hit the Fla state line where the temps are pushing 80, pull over and let air out of my truck tires and 5er tires, (THAT ISN'T COLD AIR PRESSURE CHECK), .I'd wait the next morning and re-check cold air pressure and adjust accordingly. It's there for the research.
