Tire Pressure
Live in our Fiver fulltime but also have a 31' Class C. Finally want to find out the correct tire pressure for the 275/75x16 tires please. I have been putting in 75 lbs. Just cannot find the answer on...

Excellent advice here.
Gene's right about different manufacturers' charts all leading to the same result. With all the standardization going on these days that's true. Just be sure that the Size and Load Range are exact matches.
I want to point out that MitchF posted the Truck version of Michelin's chart. They also offer an RV version of the chart. Difference is that the Truck version is "per Axle" and the RV version is "per Corner." They come to the same totals and pressures. Michelin is running on the premise that RVs tend to be loaded unequally side-to-side. So the advice to get Corner Weights is good.
But if you go to the typical CAT Scale at a truck stop, you'll only get Axle weights.
Having your coach weighed, fully loaded and manned as if for an outing, then adjusting pressure accordingly, is a very worthwhile effort.
