Baffled on how to beat the heat? Is your RV AC air flow struggling? In this video, Kasie decides take a look inside our RV AC ducting in our 2019 Jayco Greyhawk 31F to see if we can stay a little cooler. Did it work? In this video, we'll show you the data so you can judge for yourselves.

One cool thing about this mod: she did all the RV AC modification work herself. And even better: it cost less than $20.

Turns out, this is a pretty simple RV modification. You basically need a screwdriver, knife, glue, scrap cardboard, scrap foam, and A LOT of HVAC tape. After watching this video, even I (Lana) could do it.

Here’s a link to the paper template shown here. You’ll need to download the png and then print it.

If you want to get fancy, you can 3D print the baffles. Here’s the Thingiverse link to 3D design: https://www.thingiverse.com/thing:4662142

RV Airflow Systems makes a variety of kits for various AC units, and you can find them here.
