The airbag unseating is by far the bigger concern.
Iíve come to the conclusion that itís cya on Freightlinerís part, but theyíre really adamant about this potential damage.
Iím done with this thread
Y, passing on the info is fine...but when I hear uninformed stuff like "shock seal damage" or "it's ok for a little while but not for a long time", then the rest of the source is questioned.
I agree with their conclusion that you should not lift the wheels off the ground if you don't need to. But not for the reasons cited. The real reasons are:
1) Additional sidewards leverage on the leveler cylinders. If the cylinders are wimpy, then that can be a problem if something slips due to not being level.
2) Possibility of a hydraulic hose failure. One leg drops and twists the chassis. I just yesterday replaced 4) 45' hoses on my Man Lift...they do fail.
3) The temptation for storing stuff under the RV or kids hiding underneath.
4) That if one end of the rig is up in the air, and the other is down, then that implies you are on a steep slope. Not good for slippage.
Yup, thread is beaten into the ground.
