So, I had a concrete pad put down in my yard, and I got a 50AMP service installed and started keeping the new-to-us RV in a proper environment. Then I realized I should be changing the AC air filter now and then. I read the manual...
Ok, under the bed, 10x20. I get the filters...
Then I go and find this:
WHAT!? Two filters, TWO DIFFERENT SIZE filters!
Winnebago, are you serious? Can somebody explain this?
I'm not sure of the reasoning Winnabago used. However there might be things below the floor limiting the area of each filter. So units need to breath as best as they can to function efficiently. Possibly that was as big as they could get and there is the reason. Most of the time doing AC replacements you can drop the unit size by providing a large pressure drop free return air.
