I went to weigh the motorhome (basically empty) while driving it for my first time. Someone had suggested weighing all four corners in addition to front and rear weights. The results are confusing. I double checked it. Any comments suggestions, etc would be appreciated. Obviously there is some kind of issue.

Where did you weigh?
Looks like some pretty big discrepancies between the L+R corner weights and total axle weights. And a huge difference between L and R in the rear.
I assume you were weighing corners by pulling off to the side of the scale. Was the area very flat, or somewhat uneven so that the tires on the scale are supporting more than their share of the weight?
Is that the kind of thing you're looking for, or do you want help converting the Imperial weights to Metric???

Cheers,

It was a state weigh station. I was concerned mostly about the L & R rear discrepancy. I hadn’t considered that the front and rear weights were out of line. It was pretty flat, yes off to each side after front and rear weight. I’m a total pusher rookie, so I’m interested in any information that would be useful on my journey. Thanks.

Something is not right with your weights and they don't come even close to adding up. So I guess my advice it to get some good weights and go from there.
Your front total is off by 17% and you rear is off by 29%, so I don't think your numbers are valid.
Without having seen where you weighed, I'd guess that the area adjacent to the scale is lower than the scale and the elevated tire up on the scale is supporting more than its share of the weight.
Maybe try a scale at a truckstop? At the cat scales you can go in and tell them you'll be doing several weights and they'll discount them after the first reading. They've got three scales intended to weigh the front axle, drive axles and trailer axles at the same time. So you can pull onto the scale and get two axle total weights, then move over a little so that two tires are off the pad and get a separate weight of just one side.

Most of the new cat scales are designed so you cannot pull off to one side. In that case you need wheel scales
Some alignment shops have them. Henderson in Oregon.
Even having each axle weighed helps. On a Cat scale the axles are weighed all at the same time.

Well I went to an official ODOT (Oregon) scale on Hwy 212 Clackamas/Rock Creek. They are apparently state maintained and ? should be accurate. There is a Cat scale about 20 miles away. Guess I’ll try that. Henderson from what I can tell is no longer in operation. Camping world was of no real help.
