Strange wheel weights

[jkdolan]

 

Just started full timing RVing - 5th wheel -to see the country I defended.  Did a Smart Weigh with Escapees. Weigh each wheel independently.  Chevy 2017 3500 HD. Winnebago 39FB 5th wheel. B&W Hitch is installed in GM factory pucks/holes.  Airlift Airbags Smart II System

Truck only individual wheel weights. 

 Front Left 2850 Front Right  2750  

 Rear Left 2300  Rear Right 2300   (Dually)

Pretty even unloaded. Weight in truck distributed evenly.

Truck and Trailer loaded

Front Left 3000 Front Right  2500

 Rear Left 3900  Rear Right 4600

Truck is cockeyed/unbalanced

500 lb heavy on Front Left

700 lbs Heavy on Rear Right

Logically if 5th wheel is putting weight on one side both front and back should be heavier on one side. If frame was bent it should show up when unloaded also. 

Any thoughts?

Scales and weighmaster are certified. They weigh 20-30 times month

 

Any thoughts?

I have never towed a 5th wheel but my bro-in-law has towed a 5th wheel camper for years.  He said this about weighing by tire:

 

If your truck & trailer were on an angle the true weight will be off possibly due to the scales being higher than where rig is sitting.

 

Must have a level place to put all wheels while one is on the scales.

 

I don't know if this possibly could explain the differences you are seeing but I really didn't ask him about it in detail - just asked

what reason could there be for individual wheels on 5th wheel to have different weights on scale.
