Agree...get a professional diagnosis, and go from there. I have Atwood Levelegs - electric jacks - and I finally have them back working after 2+ years.
I can say that I got proficient with the orange blocks in leveling my MH. Most important for DW was that I get the head of the bed level or at a slight up angle. All else being out of level we could live with.
I had one jack that busted the upper head and had to be remanufactured, and the control pad connection broke and I could not find the out-of-date part, except for a few RV salvage yards that wanted 3 prices for it.
I finally ran across a friend who had a Tiffin MH, and by gosh it had the exact same Atwood Levelegs control panel that I needed. He also needed one, and went to Tiffin, who had them in stock for $117. Good things come to those who wait...
