Well, I answered my own question.  Rotapax recommends mounting them on the roof.  The presenter even states in the video that mounted flat on the roof, the Rotopax has not been known to leak.  Quite interesting.  From the Rotopax web site:

I'm not arguing with you, Dennis, just pointing out what the company recommends.  Interesting that the advice here is one thing, but that to Mr. Squirrel, after he had a problem, is different.

Hmmmmm..... .
