The Fantastic Fan 807350 is the more sophisticated model with a rain sensor, digital remote, reverse, etc. Overall, we are really happy with the functionality of the fan. It moves plenty of air and is very efficient pulling about 2.5 amps on high. With that said, I think the fan is more complicated than it needs to be. I cut the line to the rain sensor as it is way too sensitive and turns the fan off randomly. In my opinion, save the money and get a simpler Fantastic Fan model.

The two large side windows are CR Lawrence awning style. Having these windows pop open allows so airflow on hot nights. The install for these was the easiest of the five that I did. I simply cut the sheet metal (not the subframe) where the window outline exists on the factory body.



  1. Take a deep breath…you’re about to cut a huge hole in the side of your new van.
  2. Drill holes every 6” from the inside to mark the cut.
  3. Tape off perimeter to protect exterior paint and cut.
  4. Touch up with a flapper disk on a grinder.
  5. Paint exposed steel to avoid rust.
  6. Install window in opening.
  7. With a partner holding window on the outside, install the CR Lawrence clamp ring on the inside.

The windows installed smoothly and have a permanent weatherstrip on the window side that creates a water tight seal.

The rear windows were more difficult to install. They rely on a bonding agent rather than a clamp for structural support.

  1. drill holes every 6” from the inside to mark the cut
  2. tape off the perimeter to protect exterior paint
  3. cut the pattern with a jigsaw on exterior
  4. Touch up with a grinder w/ a sanding disk
  5. Paint exposed steel to avoid rust
  6. Install window trim on cut edge to cover rough edge
  7. sand surface where adhesive will be applied
  8. clean all surfaces
  9. clean surfaces 10 more times
  10. apply “3M 08682 Single Step Primer” to painted surface
  11. apply thick and uniform bead of “3M Window Weld” to primed surface. Use an entire tube per window
  12. install window and apply firm pressure to entire perimeter
  13. Attach suction cups (also called dent pullers) to interior of window
  14. attach straps to suction cups and tighten to apply even pressure to window
  15. let van sit for 24 hrs


For the rear section of the van, you can use a non-contoured window. Ours is a C.R. Lawrence VW8406 41.25” x 16.75” with a 1.5” trim ring. Since the sheet metal is thin and the smallest trim ring is 1.5”, a spacer is required. I built a rectangular wood frame 1.5” thick to account for the gap. This window also does not include weather stripping. I used a rubber gasket found in the garage door section of home depot and it works perfectly.

  1. pull measurements from the floor of van to make window level.
  2. trace outline of window on interior
  3. cut window with jigsaw
  4. install weather stripping on window
  5. install window with partner holding window on exterior
  6. install rectangular 1.5” spacer
  7. install window clamp ring
