Without knowing actual weights - I would run at the placard pressure in the RV (label near drivers seat on mine)... This is based on the max gross weight of the rig.
If you know the axle or corner weights - you can adjust pressure based on tire manufacturers data to a softer - but safe - ride.
No need to run the tires max pressure unless that matches one of the above.
I'm running what the label in the RV says for long trips - verified by weights that for extended trip I am flirting with max weight...
