2007 knight leans bad on the passenger side after 24 hours
Replaced the air bags 2 years ago already

I’m seeing the most likely problem after the air bags may be the ride height valve(s) ( sensors) then the air dryer which should be changed at 2-3 years.

Thanks for the reply
Ride height valves are only for the stand when the rig is running
Air was changed last November 25
Plus my height valves have already been changed
This stuff has been going on for years

Safely get under the rig with air in the system. Bring a squirt bottle with a soapy water mixture in it. Spray the fittings and the two PPV valves that are mounted to the tank. Be sure to soak them on top too. Thinking one may be bad and leaking. Spray any and all air fittings while you’re there looking for signs of leaks. If all looks good then I would look at the air line connections on top of the air bags. Be sure to use adequate jack stands or blocking before getting under there
