Brand new RV’er when i arrive at a site with a Class A MH Do I 1 level the rig with the stabilizers then deploy the slide out 2 deploy the slide out then level the rig with the stabilizers ...
I talked with Monaco a few years ago to make sure even though my owners manual said to put the slides out then level. They said slides out first were the correct way. I air up, retract the levelers and then put slides in when departing. It has to do with the engineering of the slide mechanisms as I was told. If in doubt give your mh techs a call.
