How we stabilized our RV ladder

Our Fuzion 429, being a toy-hauler, has a ladder attached to the side. We have been noticing that some of the screws holding the ladder to the wall were loose. Snugging the loose ones up didn't last long since they were clearly stripped at some level.

We use this ladder at least three times per stop; once to put up the cell signal booster antenna, once to inspect the tops of the slide-outs before we put them in (when we leave), and once to take down the cell signal booster antenna. The ladder needs to be stable.

I had an online chat with a customer service representative via the Keystone website (www.keystonerv.com) and they suggested just trying a larger wood screw. While that may have worked in the short-term, I don't think that would be a long-term solution. Additionally, the holes in the ladder mounting brackets are fairly small so a large wood screw or lag bolt just isn't going to fit.
