This is without a doubt, the best answer.
Weigh all four corners - they will be different
inflate that axle's tires to highest the tire pressure on the tires inflation chart for the heaviest weight.
Rule of thumb:
All tires on an axle must be inflated to the same PSI based on the actual load on the most loaded wheel on that axle.
If no scale to determine the actual loads: the tire placard is USUALLY safe. Just might not be correct for how you loaded your camper. Placard inflation pressures normally include RIDE as well as "average," not maximum, loading (otherwise you would not need a placard - just a sign that says "read the tire").
