load weight
Does it seem logical that the things you put in axis should not weigh over 600 pounds. I'm not talking about people or pets, just cloths tools cooking materials or occupant and cargo and fluids about 1400 pounds. Also fully loaded tires should be 75 in front and 70 in rear?

Are you looking to see if your "stuff" is overloading the RV? The solution is simple: Take it to a scale.
CAT Scales are all over the country. I weighed ours after we loaded all our stuff up, with a full fresh water tank, full propane, the three of us in it and I was about 1,000 lbs under the chassis GVWR.

The 25 series seem to weigh more then the 24 series.
Mine is so close to its GVWR that I move as much as I can like tool boxes to my toad.
Here's a copy of my weight certificate.
My weight plate calls for 75 psi in front and 65 psi in the rear.

What air pressure is written on your tires and what weight are you using

I'm only about 500 lbs less than you Bruce:
The GVWR is 12,500 (at least for the E350 built Axis/Vegas units).

So are you running 55 psi on rear?

The GVWR on the 2016 Axis 24.1 E-450 is 14,500. That is a nice addition. Looks like I don't have to worry about all my junk. I have not had mine weighed yet. My coach calls for 75 lbs front and 80 lbs rear. That is what I am running. It came from the factory and CW with 55 in the rear.

If you have not had the coach weighted set the tire pressure to that recommended on the sticker attached to the vehicle. Ford placed that sticker there for a reason.
After you have the coach weighted set the tire pressure to that recommended by the tire manufacturer.
If someone fails to do either of these they are subject to finding themselves with one or more tires having premature failure. But then I guess it will be the tire manufacturer or Thor that is at fault and not the owner of the RV.
As a note, the tires for my rig change pressure by 5 PSI for every 150 pounds of change in weight.

The E-350 may only be at 12,500 pounds GVWR, but the rear axle is rated at 8,500 pounds according to Ford specs. That leaves a lot of capacity compared to Jamie's 6,700 pound load. Almost a ton to spare.
Granted if you loaded the rear axle to full rated 8,500-pound capacity you may exceed the 12,500-pound GVWR, but what would that really mean in practical terms? Specs on E-350 and E-450 are essentially the same except for heavier rear axle (9,600-pounds) and springs. Even tires are the same.
It seems some of these ratings are driven by need to meet government regulations more than actual equipment limitations.

Is there a weight vs tire pressure graph for Vegas/Axis? I have never seen one? What are the issues of having the tires at the manufactures recommended tire pressure, as long as you stay under the GVWR even if you are 1000-2000 lbs under the max? For the E-450 chassis that is 80 psi for the rear tires which is max for those Michelins.

The load vs tire pressure is not based on RV model but rather based on the tires.
Here is the link to the Michelin Chart for RV tires
Michelin RV Tires | View Michelin RV Tires load and inflation tables for motorhomes and recreational vehicles. | Michelin RV Tires
The table represents axle ends so if you do not have 4 corner weights multiply the weight by 2 to get the axle weight.

Michelin load tables for my tires would have the "minimum" pressure for the front tires based on actual load way lower than Ford recommends. I've backed off Ford's recommendation a little (5 PSI) to soften the ride, but I wouldn't want to drop the pressure to the minimum required for the load because of other factors. While the tire may carry the load fine, it affects handling adversely. In my case it's one of the disadvantages created when the manufacturer uses tires that are much larger than required for the given load.

I can't remember what I was running in the tires. I checked them at the beginning of last season, then once or twice throughout the summer--they held.
I'll check them again prior to our first trip this year. I do believe, though, I had them setup similar to Onielkeys: 70ish in the front and 80ish in the rear.

That makes sense with my GWVR at 14,500. The chart indicates that I can reduce my tires about 5 Psi for every 300 or so lbs of weight per axle below the 10,000 or 5,000 lbs max. I now need to weigh the Axis to decide if I want to reduce the inflation pressure in my tires. The Axis is riding pretty comfortably at 75 and 80 psi but I can't see where it will hurt to reduce the pressure in the rear tires to 75 psi, as long as my weight is not above 9-9,500 lbs or so on the real axle. If I do so, it will be interesting to see how that affects the temperatures the tires are running at. Thanks for the chart.

tire weight
Do you take the rear weight and divide by four?

That would give "average" weight per rear tire, but most tire tables aren't set up like that. You'd have to convert which is more work.

Is there a weight posted anywhere other than the one Thor puts by the driver like on the truck?
