Rear Air Pressure Low in Dutch Star
Hello I got a 2000 Newmar Dutch Star 3851 on Spartan chassis that I was going to drive from my house to storage today and noticed during warm up that the rear air tank gauge was just above zero and...

Well I got a chance to check some things out and here is what I found:
I raised the jacks and MH sat on deflated air bags. I started the engine and let idle.
After idling the front tank went slightly above 125psi when governor kick in.
Rear tanks stays at 25psi with a red light in the gauge but no buzzer sound.
Low air buzzer goes off after about 70psi in front tank
MH air springs raised at all 4 wheels.
I found the lanyard for the tanks and pulled on the one on the passenger side and it sounded strong. I pulled on it for awhile and check both air gauges (left ignition switch on engine off) and the air in the front tank was at 75 psi rear was still at 25 psi.
I started engine again until the front tanks reached 125psi and I heard the governor kick in then shut off engine and left ignition on.
I then pulled the lanyard on the other tank for the same length of time (90 seconds) and it sounded the same as the other tank. After 90 seconds I checked air tank and front was 75psi and rear 25psi.
I started engine and ran it until the air tank was again at 125psi then shut it off and put the jacks back down.
I am thinking it might not be the threaded rod for the height sensor if the rear suspension raises and lowers. Also from the sound of the air being released from the air tanks I am hoping it is just now a gauge issue.
I am wondering if it is safe to drive it to the shop.
