Yep, there is a particular key code (that we probably shouldn't mention here for security reasons) that I daresay will open the storage compartments on more than 80% of RVs. Another one of those things that make me go, hmmmmmm.....
I guess the upside is, if (or when) you break a key, more than likely you can get your neighbor to open your storage bays for you.
