Keep it simple... Use what’s on the pillar for your first couple of trips. If you find the ride too harsh, get it weighed and use the real weights to adjust the tire pressures based on the tire chart.
After a few trips you will know what you bring, and then you can get it weighed if for no other reason to verify that you have not overloaded it.
The sig 1991 Class C is overloaded at the back with nothing else in it. I have to go over the door PSI for the back tires to meet the actual weight as seen on the scales. I can do that higher PSI with Es instead of the OEM Ds the door specs call for.
I don't think Ford, who made the "incomplete truck", expected the RV maker would build a house on it that sticks so far out the back, that the leveraged effective weight on the real axle is so large.
It might not show up so much on a 22 foot Class C, but it sure does on a 28 footer.
