This is in regards to that 2005 Beaver I looked at today but it's the same 2000 series HWH system that's in the multi-slide unicoaches (02+, I think) and I need to bounce a couple thoughts off you guys so just pretend it's a FT.
It has a single ride height control valve at the center of the front axle. It ONLY dips in the front right corner when in travel mode. The other side airs up fine. That rules out the ride height control valve as the culprit. I wasn't able to see it dip when put in travel mode, so that makes me think it's intermittent. The front right travel solenoid gets VERY hot when in travel mode. Noticeably hotter than the left front travel solenoid. I'm pretty sure the solenoid is failing and I suggested he swap the coils left to right and see if the problem follows but I think he's just going to replace it with a new one instead.
Before he goes through the trouble of replacing the solenoid, can anyone poke holes in my diagnosis or suggest an alternative cause? I sprayed around up front and his rig is really air tight, so I'm confident it's not a leak causing it (I'd be able to hear a leak big enough for the engine air compressor to not be able to compensate).
If HWH air leveling, may be a defective solenoid/seal or signal on/to the front 6 pack.
Also make sure all electrical connections are tight. I had a plug come loose on me once and it would cause the same symptoms. Just a thought.

"Which is exactly what Brett said" guess I should read better first!!
Eventually having pressure gages on each corner will reduce trouble shooting time. Especially once you know your normal operating pressures. Think your going the right direction
On my Foretravel, replacing a solenoid is a simple procedure. So I'd go with that.
