Wallowing Beast
My new to me RV runs and drives well, but definitely feels wallowy, overloaded and top-heavy. It's somewhat unnerving to drive, though once on the open road it seems fine. I have never driven one of t...

Problem with that is, in most cases the RV manufacturer will simply repeat the Chassis manufacturer's recommendation. And that recommendation is for the maximum loading the chassis manufacturer specifies. If our specific RV, loaded and ready for the road, people, food, clothing, supplies and all, is less than that max weight, then our tires are overinflated for our actual load.
One tire manufacturer's chart (such as Michelin's that's so easy to find) will work for other brands, so long as the tire specs match.
On any vehicle, there's an ideal tire pressure and negative consequences in ride, handling, wear, and possibly failure (those Ford Explorer blowouts!) for pressures that are grossly wrong. As a Ford E-Series owner, I'm acutely aware that FRONT tire pressure has a huge effect on steering stability. There's a narrow spread either side of the charted rating, seems to be only about 5 PSI, where stability is best.
Other chassis brands don't seem to be as touchy as the Twin-I-Beam Fords, but there's still an ideal pressure, and the number on the sidewall (repeated by vehicle builder for liability purposes) usually isn't it.
