Just purchased 2002 Workhorse P30; front airbag question

Winnebago specs 65 PSI in the tires. As long as I run speced tires (I am) and don't exceed plate weight, I should be fine. Too much tire pressure can stiffen sidewall if it is needed, but can also give the bone jarring ride I want to avoid. Hopefully my add-ons will give me the stability to run 65psi. The rears had 80 in in, and when I let 15 pounds out I was much less affected by trucks.

Truck stops weigh per axle, but how do you weigh a single corner?
