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.
Recommendation,
- 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).
Happy camping.
