You need the ride height adjusted all the way around. This is done at the 3 ride height adjusting valves, located near your wheels at the outside of the frame rails. They need to be adjusted on the chassis rise, not settling, and it can be dangerous for someone who doesn't know what they are doing. A wrong move could drop the RV on you when you are under it adjusting. Get it done by a professional at a Freightliner dealer or a good alignment shop.

John is offering good advice, I hope you heed it.

do you have the measurements? where to exactly measure and what is (chassis rise not settling). Do you think that I could measure from the floor to chassi beam?

Ninos...the measurements are different for different chassis. If you call Freightliner they will not give you the measurements due to the danger of someone with no experience trying to change them. Please take this serious. Two choices, delay your trip and have the height adjustments done professionally or have your family delay theirs with you in the hospital or worse.

Please...if any of you DIY's out there decide to chime in, please think about giving information to a novice that could possibly kill him.

Ninos, Your ride height depends on which Freightliner chassis you have. Your chassis model will be specified on your vehicle data sticker. It'll show as XC-F, XC-M, XC-R, XC-S. Each of these may have differing heights and the place you measure it is different. Measurement is usually done from frame to shock mount point, but the specific points vary.

What I meant about the frame raising is that once the ride height control valve is disconnected, it's positioned manually so chassis is lower than it should be. Then the valve is adjusted to allow the coach to raise to the correct measurement, the valve adjusted and then the system re-assembled. If your manual adjustment causes the coach to raise too high, you have to re-position it to below normal before you bring it up to the spec measurement, rather than just bring it down to spec measurement. Adjust on the rise, not the drop.

thanks a lot that really helped. Called frightliner today and they give me the measurements no questions asked and they told me exactly where to measure. Thanks for all the help.joe
