I just bought a 2013 NV 2500 HD that I plan on turning into a camper to live out of for a while after college. It's going to be an "outdoor special" with space for bike storage and other gear. I had an old Chevy Express before and wanted to upgrade to something newer and taller. Does anyone have any recommendations for roof vents? I had a Fantastic Fan vent in my last van and it was great but I would like to find something bigger (something more like a skylight). I've looked into boat hatches and other such openings but those are a lot of $$$. Thanks.
