I want to do this as well for a skylight or additional fan.
Thanks

I did cut a new hole for this fan and also one in the bedroom (for a fan-less vent). I think you can see the pictures if you go to my "troutslayer" site and check the photo album section. But basically, this is what I did:
FIRST, I emailed Jayco to get the roof framing schematic so I could see where they framed for the cut-outs. I'm not sure how seccessful these installs would have been without this framing. The electrical wiring was run, by the factory, right next to the cut-outs.
After making the inside cut-out, I drilled the four corner holes.
Then, went on the roof and scored "X" lines in the EPDM roofing material connecting the 4 holes, folded the roofing membrane back and made the cut-out with a sabre saw (tip: taped a plastic bag on the inside ceiling to catch most of the sawdust).
After the hole was cut, I folded the roofing membrane "triangles" into the hole and stapled them to the framing (prior to this, I stuffed the cut-out insulation around the opening).
Installed the roof vent flange using Butyl tape under the flange, lining up with the center of the screw holes. Pre-drilled and installed the screws.
Covered the flange with 4" EternaBond tape and coated the edges with Dicor for extra protection.
Installed the roof vent fan.
Went inside and wired up the vent and installed the interior trim ring. I didn't need to trim the interior trim housing because the roof thickness was large enough. As a matter of fact the FantasticFan shroud was about 1/16" too short but hardly noticable so I didn't purchase a new one for $25
.
In my opinion, the MaxAir Fan is a better product and was easier to install. It also was about the same price as the FantasticFan if you include the FantasticFan cover (which is quite pricey).
It's a fairly easy job, just need to take time and think through the process. Send me a message if you have any other q's or cannot see the pictures. I'd be glad to send them (or post).
