Are Our Tires REALLY that sensitive?
I know I will roust the ire of many a tire aficionado, as well as those who will claim expert knowledge from years of traveling and RV'ing and quasi-engineering or actual engineering status/certificat...

After owning a TPMS for about a year, I can tell you this, the temperature and PSI swing of these tires is amazing. Add to it that it's very likely you will leave at one ambient temperature and arrive at something very different. Unless you stop once an hour and let the tires cool down, re-check, and adjust accordingly, you are basically within a range. A very wide range. So I agree with you, check them cold when you leave and you are good. The parameters for these tires vary so vastly, even on the MH that close enough is the name of the game. Heck my one front tire closer to the manifold and genset always runs 5 degrees hotter than the rest. The inner duals run hotter than the outers due to less airflow. Setting it before you leave is the best you can do. While travelling they experience such a range of terrain, temps etc and fluctuate accordingly, outside of auto adjusting constantly, they do what they do.
