    So bit of a update, vibration came back feeling it mostly in the floor. Clutch no vibration what so ever. Been tinkering with it hear and there and so far I’ve the leveling valve constantly going up and down like a 1/16 to maybe a 1/8th of inch all the time. Found some posts on hear about adjusting ride height so definitely looking into that when I get home tonight. What would the leveling valve to constantly do that?

    The valves get sloppy sometimes, when they get old. So when they get centered they’ll still be dumping or adding air. Like they’re sticking. Hearing them adjusting after parking, or while dropping/hooking is normal. As long as once the height valve settles, height stays the same.

    They’ll leak constantly when bad.

    Leveling valve was indeed bad, thanks for that info. Also found a crack under fifth wheel plate so getting ready to pull fifth wheel and slider rail to fix that and get entire frame sandblasted so I can paint it. Guess it’s a good thing I do enjoy tinkering and working on the ol girl lol. Thanks for the replies guys
