I found this under the coach.
Back story, went to storage and the left front would not raise. When stored for an extended period I put the safety stands in, so had to raise the coach to remove them. Ordered a new solenoid and installed it today. Left raised just fine. Pulled the safety stands dumped and then went into travel mode just fine. Backed the coach out of storage and found this.
Coach ran just fine coming home (~30 minutes including Poncha Pass). I got home and the DW said isn't the front kind of high. No indication on the trip home of an issue with travel mode. It could be the place it is parked makes the front look high.
Tom, that looks like the piston of a solenoid valve. The blue center seals the air flow when the coil is de-energized and a spring in the other end of the tube pushes it closed and holds it there.
The six pack valves have a piston similar to that one but I can not say that is where this one came from.
Hum, that's definitely a plunger from one of you HWH six pack vale/solenoid.
I'd take a close look to make sure all solenoids are in place on your front and rear HWH leveling six packs...

That plunger fits inside one of the HWH solenoid valves. It couldn't just accidentally fall out on the ground - the valve must be completely disassembled for it to be removed. See photo below for disassembled valve. The solenoid coil fits onto the chrome shaft. The chrome shaft must be removed from the brass valve body to reveal the plunger and spring.
See Reply #53 for the full disassembly sequence:

Thanks everyone. The complete new solenoid unit has been installed and seems to be working fine. Thanks for the quick responses.
