I understand that you are weighing on a single platform scale. You easily got your total weight and you could, if needed, only weigh the front or backend on that single platform scale. That and some simple math could have gotten you axle weights. If you can get back to that scale try weighing the front end, the total, and then the rear end. If you can't do that, look on the web for CAT scales and find the location nearest you (usually at truck stops). CAT scales have three platforms and will weigh your axles individually in a single pass and for about $10.

You can then, with the use of a calculator and tire inflation tables determine what is correct for your coach. The calculation is simple:

Axle weight + 5% (this compensates for side to side differences) = Corrected axle weight. Divide Corrected axle weight by two for wheel weight and use your tire tables for the proper inflation pressures. Add 5 PSI to number for a safety/fudge factor.

Your dual axle is the same as the inflation table usually lists dual tire pressures as a pair. If it doesn't, then divide by 4.

Once you have done this, you have determined the correct tire pressures for your coach and your load.

My listed weights were done on a CAT scale, very nice for $11.
In this case, I could not weight each side of the same axles.

Also be sure you DO NOT EXCEED the max tire pressure stamped into the wheel rim itself. I've seen what happens to someone who had tires that required 110 psi but the rim was only rated for 90....BOOM! It was an older rig from back when tire pressures were relatively low compared to today's.
