A/C return grill?

[mainvetteman]

So my friend purchased used 2016 3750 FL Bighorn. It has the Dual roof Air with ducts. However we cannot figure out and cannot find the return grill. Anyone have ideas?

Hi mainvetteman,

Welcome to the posting side of the forum.

The return air is through one row of the ceiling vents. If you look closely you will see that they have the filter in them...or should have, and I think usually it is the outside row the is the return vents.

Correct - one side is inflow and the other is outflow. You can feel it with your hand when the AC is running. I think its a lousy design.

When you visually inspect the air ducting, the intake vents SHOULD have a filter material over them. Folks have reported that, from time to time, the filters have been installed in the output vents which is NOT correct.
