roof vent in ford van

Seems like the relevent forum for this question, I want to add a powered vent to the rear of my 1998 Ford E350 extended van. It's mostly a tow vehicle and motorcycle hauler, but it's also a mini-class B when I throw in a cooler, the coleman stove, a porta potti and a foam mattress for the night. :)

It gets awfully hot in there, and I am often stealth and don't want to open up the rear doors for ventilation overnight so I want to add a fan. I'm debating between putting a fantastic fan in the roof, or in place of one of the rear door windows (it's a fully windowed passenger van).

I'd prefer the roof from a security/aesthetic point, but I have rear air conditioning and the ducting is in the ceiling. I've not pulled the headliner to check, but it doesn't look like theres much room up there to fit a 14x14 opening.

Has anyone here added a roof vent to a passenger van with rear air? Thinking I could just offset it to the passenger side, would that look too weird? And the roof is not as flat on the sides. Anyone done this? Do any factory conversion vans install a roof vent not centered on the roof? Or do they all have fiberglass raised roofs?

Anyone installed the fan in the rear window? It would be installed in a sheet of plywood then installed in place of the window. Always closed when driving, just open and running when parked and sleeping in the back.
  • You don't need to center a vent. The mounting needs to be reasonably flat, not perfectly flat. Most RVs now have a curved roof, and mount vents to the side of center.

    Looking "too weird" would be a matter of your own taste, but if there are any passenger van fashion police, they might not approve of any roof bubbles at all. A vent in plywood replacing a window would certainly look more weird than on top.

    The. vent will mount to exterior skin, a trim piece covers the open in headliner and whatever is between. The trim pieces come in different depths for different ceiling thicknesses.

    I see a lot of work vans, cargo vans, with multiple 14 inch vents. Just gets too hot here for an electrician, plumber, A/C guy to work in his van without venting some of the hot air through the roof.
