How often do you check your Truck's tire pressure?

When traveling, I check every morning when the tires are cool. I pay special attention to the front tires since all trucks with coil springs and solid front axles are susceptible to "Death Wobble" if not kept well inflated. On my E rated tires I run 75 psi in the front loaded and unloaded and 80 in the rear loaded, 60 unloaded.
