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 ...
A lot of manufacturers want the body of the coach to be square which is why they want you to put the slides out first then level. Once you level, you could be making the frame of the slide a little less square but it's now locked in holding everything tight.
