Which PSI rating to go by
Okay, so now I'm confused. When airing up tires on trucks for towing, do ya go by the sidewall PSI or door data label? I always thought the door label was lower and yet sidewall says max "X" pounds at...

Yellow sticker is the manufacturers recommendation based on the rated weights for the axles / overall vehicle weight when loaded. That should correlate with the chart Burbman posted. When you are unloaded and have less weight you can reduce the psi. Running at the correct psi provides better ride comfort and tire performance (grip, braking). Now that I have that TPMS the darn thing glows on my dash when I air down to where I want to be so end up running higher psi than I like when unloaded.
