The
Fiber Stream originally had a stationary panel for the upper
fridge vent.

Before
I had read about other members adding an exaust fan to help the
fridge cool when the ambient temperature outside was above 90 degrees. I had such a problem last summer in Palm Springs when my
fridge would only maintain 50 degrees inside, turned up to maximum.
However, when I removed the panel to access the space for the fan, I found that the fasteners along the sides of the vent panel did double duty,
also fastening the back if the fridge cabinet to the shell of the trailer. When I removed the panel, the shell "relaxed" and moved away from the back of the cabinet, opening a 1-1/2 inch gap between the cabinet and the shell, and exposing the burner to the living compartment.
The interior of that vent space was all wood, and was dry-rotted from the exaust gasses.
I found a new
hinged vent access panel, slightly smaller than the plain one. The cut-out in the
fiberglass was small enough for the new panel. I used the original screw holes to install screws to re-attach the body of the trailer back to the back of the fridge cabinet, and installed snap-caps over these screws.
I lined the interior of the vent area with sheet aluminum.
Then I installed the new vent access panel which has a plastic insert piece around the perimeter to cover the mounting screws.
And finally, I mounted a 12 volt fan inside to pull the exaust out and help the fridge maintain 40 degrees even in the hottest weather.
