Problem solved, I called Thor and they told me how to do this. I removed all for ladder support brackets from the motorhome. behind the ladder support is a Phillips head screw that tightens into the ladder, then the entire bracket gets remounted back on the coach. Not a hard job, recommend two people to do this, And a separate ladder parallel to the one on the motorhome to do accomplish this job. The ladder is now tight and can hold me.
