Some "overthinking" going on here. The tire manufacturer engineers have already looked at these factors and taken them into consideration when the published the Tire Inflation Charts.
Weight the coach (4 wheel position best). Use heavier wheel position on each axle to to to the chart. The chart number is the minimum PSI for that weight. Add 5 PSI to it for a safety factor. Adjust seasonally with big swings in ambient temperature. PERIOD.
Again "cold" pressure is pressure at current ambient temperature-- be it 30 degrees F or 100 degrees F. Same for all tire manufacturers.
