With campers, towing, truck camper or any high payload weight you will also need to keep an eye out for pressure going UP.
In the desert on hot pavement your tire pressure can double easily. Tires are usually fine up to double the max pressure stamped on the side just to cover any defective tires.

I have driven at 65-70 mph for hours at a time in temps as high as 108 and have never seen my 80 psi tires pressure rise more than 10% or so. So hot that my tires stuck to the hot soft asphalt at a rest area and I had difficulty getting them unstuck to start rolling again. :E
