I never liked our setup,,, but could not find another way to level,,, used blocks & wood under the power jack + under the stablelizer legs which were out as far as they could go,,, then I would put a little weight on the legs,,, Did not look safe at all !!!
Our Flagstaff did not have leveling jacks,, they were only for support,,, do not remember what they were called ??? Good Luck & Be Safe !!!
Best to find another parking spot,,, We spent almost 2k for drive way extension,,, to have a level place to park MH !!!
