What is puzzling is mine is also built on the Ford F53 chassis. The previous owner replaced the tires in 2014. On the sidewall of the tires it says minimum air pressure is 100 lbs. On the placard on the drivers side wall it says 80 lbs. I think I'm going to post the type of tires and ask for feedback. It may very well be I've got cheap hard - overinflated tires causing the rough ride.
Sorry, that is NOT what it says on the side of the tire. It will say carrying capacity of XX at YY PSI.
If your tire is not carrying XX, you do not need YY PSI.
Go get your coach weighted-- individual wheel position weights are best. Then go to your tire manufacturer's inflation table to determine the minimum PSI for that weight (all tires on an axle get inflated based on heavier wheel position on that axle). Most of us add 5-10 PSI to that minimum.
The GVWR sticker by the door will give PSI for the coach WHEN EACH AXLE IS LOADED TO GAWR. Are you that heavily loaded? If not, that may be over-inflated.
