Hi, my name is ***** ***** you for your question.
Has it been like this since new?
Has anything changed or added to Rig?
Do you pull anything behind it?
I'm sure this has been checked but tire air pressure all the way around?
Looking at rig from about 30 ft distance is there a downward angle from rear to front with rear of rig being slightly higher?
Also look from side to side for any difference same distance from rig?
Any odd tire wear?
Is it loaded with gear?
Let me know

Hi my name is Robert...
I would be looking at the ride height to make sure it is set a factory specs, if the drive angle was off you could get vibration in the front or rear. Sometimes the valves can settle when they are new or you replace them and drive the unit they always have to be rechecked. I do not have the specs on that normally you would measure the air bag height from plate to plate and it should not be off more then 3/16" from side to side.
I might have the dealer look at this if it is a 2015, they need to drive the unit and duplicate the issue, if it is a 2015 and something is going on it should be covered under warranty.... Hope this helps some.... Robert
