Often the techs will set your tire pressure at the maximum cold rating written on the side of the tire and you will also find the coach manufacturer will us the maximum inflation numbers on the vehicle weight I'd placard behind the driver's seat on the wall . In both cases they do this to limit their liability as they have no control on how you load your vehicle .
Remember as the weight goes up the tire pressure must be St to match the tires weight carrying ability for that weight, the only way to get that right is to weigh the vehicle at each wheel position and compare the weight to the tire manufacturers load chart for that given tire .
As a rule of thumb you take the heaviest side per axle add about 10% and use that tire pressure for both sides of that axle this gives you a safety factor.
If the torque rods are worn out that is the first place to start on your journey to handling improvements.
