Matrap27 · 12-21-2018, 09:06 AM

We have a 2011 Montana 3150. We don't camp much in the winter until this year. I have read on here where the vent under the stairs need to be left open for the return air for the furnace, but what about the vent under the fridge it draws air when the furnace is running also. I was wondering if this one could be blocked off as that is where alot of the noise comes, or at least put a good pleated filter in there?
Thanks
Mark
