handye9,
Thanks for the reply. I'm not having any luck getting any information from the manufacturer so I'm guessing I'm going to be on my own when doing this. I really don't mind cutting into the roof, I just know there's not a lot of room to fix it if I mess up cutting the hole. I like the idea of the 4 small holes and the X cut on the roof membrane. It's more like what the factory seems to do ... at least the ones that I've had to replace the original vents on.
I also need a day or so where I have the time and the weather is cooperating.
Thanks,
