^ Agreed!
As for pressures, no worries about your wheels holding max pressure, but as jimlin said, you won't use anywhere near the capacity to require it.
For unloaded driving, front and rear somewhere between 30-40psi depending on your preferences. Front will be heavier, empty trucks like more psi up front, less in the rear.
Towing, even if you run a wdh, you shouldn't be putting much if any more weight on the front axle than empty. Keep the 40psi or so. Maybe bump up a bit if you want tries a little stiffer.
Rear, loaded with trailer? Depends on actual weight, but you should never need more than 50-55psi with your 1/2 ton unless you're significantly overloading the rear axle.
By your responses, op, you appear to be a set it and forget it type of consumer.
This is ok, sort of. Tires are flexible, lol. BUT, you will notice the difference, positive or negative, with the right or wrong pressures for the load, if you play around with it and take note.
