Now my question. Since it’s in the low 30s now, should I inflate to 100PSI before I take the RV out for a spin? If I understand the above posts correctly, the PSI will go up when the tires get warm from use. And we’re planning to drive from WV (cold!) to FL (warmer) for Christmas.

Small changes in ambient temperature result in small changes in cold tire pressure and are not enough to worry about, but I would bump those 90 PSI tires back up to 100 PSI in your new colder area.
