My coach has been weighed and according to the tire manufacturer's PSI chart, I should be carrying 80 psi. But, when you (or I) have new tires installed, the tire company insists on pressuring up to t...

Sure, you can gamble that you will get a better ride by running your tires at lower pressures based on the axle weight. Actually, your load rating will be closer to a lower rated maximum and the factor of safety will be less too. Will you get a better ride? I'll bet you couldn't tell the difference. It's all in the mind. It's better to inflate the tires closer to the maximum sidewall rating because you will have more safety factor and lower your chances of a blowout.
Really, that's how it works. GM says I should inflate my car tires to 33 psi. Max pressure listed on the sidewall is 51 psi. So I should pump them up to 51 psi and if it feels like I'm running on wooden wagon wheels it's all my head and I'll be safer and have less chance of a blowout.
Winnebago says I should inflate my tires to 80 psi front 85 psi rear. Why would they say that if it's safer and less chance of a blowout to just pump them up to 110 psi?
Suggest you do a little homework and see what bad affects over inflating yours tires can have. Tire manufacturers don't put out tire pressure charts based on weight just for the fun of it. If it was that simple they would remove the 'MAX Inflation xxx PSI' and replace with 'Inflate To xxx PSI' and be done with it.
