Sparkr, I think the challenge you have in asking folks with a similar RV what pressures they run is that there can be variations in tires: manufacturer, size and load carried for each vhicle which might make a simple answer like "I run my tires at 95psi" less applicable to your situation than you might think. Then, as you mention, there could be certain driver's preferences for a softer or harder ride.
I do think you are always smart to get a CAT scale weight and see what load your tires are actually carrying. There is usally a surprise there in that information somewhere. We usually think we are "lighter" than we are.
One more thing: I previously wrote "Your GCWR seems to be about 22,000 lbs..." I made a typo here and meant GVWR. Sorry for any confusion.
No tombstone says I wish I had spent more time at work.
