Ritchi flush mount compass install?

 Anyone install one in a OB? I've seen pictures of one installed in an Adventure or Revo, but can't recall seeing one in an OB. I'm picturing installing one in the bulkhead in front of the drive well, to one side (TBD)
I think I'll still be able to read it when installed there. Pictures anyone?  Also, I transport my OB upside down on my campershell, this particular compass has a dial instead of a "Ball" I don't think having it upside down will damage it or hinder its operation, (How many times did the box flip over during shipping to it's final place of sale?)  It's just a concern that I thought of when looking at a picture of it.  Anyone know any different?
