There are other uses for that fan:

I'm smart--so I added TWO little muffin fans when my original
failed.  They were side by side, blowing up from the bottom.
Well, they didn't work as well as the original, so I got another
of those and replaced them.  My hunch is that there was an
interference pattern in the parallel air flows.  That was years
ago; I've been happy with a Vitrifrigo for 8 years.

The problem with the Dometic is that it is too small.  Volume goes
by the cube and area by the square.  A big side by side in a
motorhome works fine.  Large volume in relation to the surface
area that leaks the cold out, or the heat in.  The Dometic has
too much surface area in relation to its volume.  When the van
temp goes past 110 in Moab, there is no hope for the Dometic.
