Little by little I am getting to know and love my 2009 2551 PC. However. There is a great deal to learn. I have leveling jacks and a sani-Con system that are foreign to me. I am very old school and was weaned on gravity dumping and wooden or plastic block leveling. But, I will bite the bullet and master these newer technologies. What has me stumped now is the small, lower passenger side storage area that is equipped with two Southco locks requiring a Southco key. Of all the locks on my coach, only this storage area uses Southco locks and key. Is there something about this particular storage area that I am unaware of. The factory is sending me a spare key because my favorite locksmith cannot find such a slug.
