Since you have not received a response here is my recommendation.
Nobody out there has their rig loaded the same as you so the weights will be different and thereby tire pressures may be different.
- Load your coach for travel to include pets and passengers
- Have the coach weighted. 4 corners weight would be preferred but a CAT scale axle weight will work
- Set the tire pressures to that which is recommended in the tire manufacturer's weight to pressure table for the brand tire on your rig
- Have the coach aligned when loaded
In the absence of the above, set the tire pressure to what is listed on the labels on your door panels (manufacturer's recommendation).
