I never got a good answer from the factory for their purpose of the boards.
A fellow who I consider 'in the know' said they help prevent cavitation of the air at the top of the box from the factory fans. Your guess is a good as any.
Yes, the relay attached to the right rear lower of the refrigerator is where I got 12v. It supplies the voltage for the factory fans.
I didn't take pictures as there are LOTS of discussions (here and elsewhere) about adding fans to a slide-out mounted refrigerator with photos. I could take some if you feel necessary.
The objective with the fans in a slide-out mounted refrigerator is to create enough air flow to simulate the natural air flow (heat rises) obtained when a refrigerator has a roof mounted top vent. You don't want too much though where it disturbs the flame mixture when on propane.
One fan at the bottom blowing up and one at the top, blowing out the upper side vent, does the trick.
With this set-up it should be able to hold a sheet of paper to the outside of the lower grill when they are on.
There are TONS of fans available on the 'net. Pick your favorite flavor.
is one I used.
