Those with auto leveling systems

I run into this problem with my Montana 5er all the time. After many times getting error codes, my dealership repair shop guy finally told me those Lippert Leveling systems do not have much tolerance. You need to get your trailer as level as possible, side-to-side before using the system. That means ... ALWAYS setting up the 5er just like we did with the 3 previous trailers... with a carpenters level and lumber under the tires.

Mine has a tolerance at 2 degrees. When it hits 3 degrees, the auto level does not work. I carry lumber and level as close as I can (side to side) wherever we go before extending the jacks.
