Note to self, get on the roof and see what brand vent fans you have before ordering vent covers. I ordered fantastic covers before I checked and discovered I had Max air fans.
Live and learn. I was able to return them to Amazon (plus shipping) and order the max air fanmate covers thru camping world. The fanmates are incredibly easy to install, as they are designed to interface with the Max air fans.
On another note, got the new build gremlins addressed but found a few more I'll save until we get a few more trips under our belts.
