I just cut a huge hole in the roof of the van! Scary. It was actually a lot easier than installing the ladder though. I traced out a 14″x14″ square, drilled two pilot holes, and made the cut using a jigsaw. Done.
There are basically two main options for an RV fan. You either get the Fan-tastic or the MaxxAir. I opted for the MaxxAir, primarily because it’s supposed to work in the rain. But also a little bit because my name is Max. There’s a great installation video on YouTube that I followed. I love the YouTubes!
