Product review (4 stars): Works great for RV vent kit for washer/dryer combo
We installed this kit in a 2017 KZ Durango 5th wheel RV.  It was a fairly simple install requiring just a hole saw, some tape to stop cracking and some silicone.  The vent exterior cover blends into the side of our RV and looks like it has always been there.  We haven't had the chance to run the washer/dryer combo yet but satisfied with the vent kit so far.
