How are you? I'm FAN-tastic.

 Here's the hole I cut in the top of the trailer for the Fan-tastic fan that I bought.  This thing is totally sweet.

Blows air both ways, has three speeds, and was designed for a much larger RV.

This thing puts out a serious column of air.

Why did you cut a hole in the top of your trailer?

Oh, that's why.

 Close up of the fan.  This thing could probably lift the whole trailer off of the ground if I put it on setting 3.

More fan action.  Does this shot remind anybody of that scene in Willy Wonka where they drink the fizzy lifting drinks?
