I have a Holiday Rambler fifth wheel. There is a 4.25" x4.25" square battery vent under the front overhang. The vent has a black vent hose attached to it. The hose comes from the battery box. The vent is round but it sits in the middle of the square fixture.
The front of the vent had some plastic slats that are breaking away. I have done some web searches and looked in a large RV parts catalogue I have but I can't find a replacement.
I can find round vents, but not square ones. Does anyone know where I can gat a replacement? Hopefully it is available and is easy to replace. Thanks.
