Well Sikwan after all this time I finally did just that; removed the ducting from the rear A/C.
Looking at your sweet set-up, I'm wondering if you custom installed those louvers on the rear A/C unit?
I'm about to install a MaxxFan, but am planning to remove most of the headliner, as it needs a good cleaning. Browsing the forum a bit the situation for removal seems unclear. Would you have to remove the rear A/C completely to take down the headliner?
Also wondering about cutting thru the roof!
Here in SE Alaska this could be risky, since I'm a shade-tree mechanic, without the constant summer sun to make shade....
What kind of blade is best for the roof hole, and how do I ensure the headliner fabric is cut cleanly and centered beneath the hole?
