Another Tire Pressure Question

[Dale Walker]

Gentlemen. we just returned from AZ. and I'm here to tell you every one of the states from AZ. to MI. has these places where even 25 mph, is to damned fast! I have been and always will be a 120 psi. believer, you will never blow a tire from to much air. My Beaver, drives like a dream, but these roads are the pits, and some of these roads feels like you fell into a pit!

I'm discovering issues with the air suspension in travel mode.  That coupled with the old SMC hydraulic jack to axle system and locally designed control system, has caused me to have misleading for the last week or so.  Today we spent most of the day driving with about a 10 degree list to Port.  Thought is was a ride height problem but the RV repair guy I found discovered that there is no air going to either rear height sensor.  So I will update the thread when I know something.

Ken Carpenter at BCS said it sounds like the "6 Pack" but what is that and where is it is the next question.
