converting to a powered roof vent

Our new Chateau has two manual ceiling vents manufactured by Ventline, model VDO432. We would like to convert the rear one that is within two inches of a ceiling light to a powered unit. The service manager at the RV shop said I could easliy use the power from the ceiling light to power the new fan.
Have no experience with these fans or the others that one hears so much about like the Fantastic line. Can I get some input on these conversions and what type of fan is best to use. A manually opened 12 volt electric fan with three speeds would be adequate for our needs.

I am planning to add a Vortex II to the one non-powered vent I have. Power to come from the adjacent 12Volt light...available from many retailers on-line

I don't want to replace the whole vent to avoid breaking the roof seal.

See:

and
Vortex II Fan Installed in RV Compare - YouTube

Best luck

Check it all out as the wiring size and fuse come from the factory to supply a light with power. One way to help that is to use LED lights on that circuit. Turn all the lights on and pull fuses so you can tell what does what.

Hi wogden,
Consider Airxcel | Maxxair |
I got rid of the Fantastic Fans and switched to this brand. It does not require a sensor to get wet before closing its' lid. With a Maxxair, the inside of your coach will not get wet. Set it and forget it. I've had two of these for years and they work as advertised. I would make the same purchase again.

Suggest you remove inside framework. Bet you will find prewired 12volt wires pushed up alongside vent frame. Remove wire nuts and touch a bulb to them, if it lights, then you have "live" wires. The "Vortex fan" is the best bet. No need to go up on roof, or break seals. All done from inside. If you don't find live wires, then you may be able to "FISH" a wire from the light fixture.

If that rear fan is in the bed area, a top of the line Fantastic fan with remote control to all you to operate the fan while in bed is, in itself, "fantastic"!

Being able to start, stop, or change the speed of the fan in the middle of then night because of varying temperatures is one of the few luxuries I find useful!

When you say "powered unit" do you mean a "vent with a powered lid", or are you simply looking for an electric fan, (or both)?
