We had the coach weighed at a CAT scale early on coming in at 39,xxx lbs., A year or two later we got weighed at a moving company and weighed each corner and each axle. Our total weight at that time was 40,029 lbs.
I adjusted our tire pressure accordingly which wasn't much different that what I already had. Actually, I was able to lower the drive and tag axles pretty good.
Our weight requires that we keep 110 in the fronts, 85 on drives and 75 on the tags. I keep a safty cushion so I keep 115 on the fronts (120 max cold) and 95 on all the rears.
To the OP, you really should weigh your coach to make sure you are running the correct pressures, but this is a free world, do what you feel is best.
Safe travels,
