Thanks for the input.
Congratulations on your retirement.

As to tire pressure, I'm not sure it's necessary (or reasonable?) to go over the listed pressure on placard. The listed pressure (unless there has been an error) is based on tires being able to handle the maximum axle weight ratings, so why go higher?

In your case, the 80 PSI you are using in front can handle 5,360 pounds, which is much higher than the maximum 4,600 pounds the front axle is set up to handle. So unless you plan to run way overloaded, why use 80 PSI?

You'll know better when you get an actual weight, but for the most part I don't believe it's necessary to run higher pressures than indicated on placard.

More often than not, a case can be made to run tire pressures lower on lightly-loaded motorhomes. I know a few who run higher pressures to save fuel (lowers rolling resistance), but I personally don't think it's worth the harsher ride that comes with overinflated tires. Too much pressure can also reduce tire traction capability.
