I've put one on a 2009 Ford Escape. You don't need to pull the whole headliner out, just drop the rear end. Not a whole lot of fun, though, as you obviously know.I picked up two 1/4 antenna whips and a mag mount on e bay. I will not drill any holes for two reasons: 1- What vehicle I drive can change day to day so being able to swap stuff in a hurry is a must. 2-I have a 2012 ford escape. I am a ford technician. To get the headliner down almost all of the interior trim has to be removed, and after countless times of doing this to replace a sunroof track for a minor squeak under warranty, im not about to do it for free or pay someone to do it.
Anyway, they came today and I will experiment with them and give a review. I do appreciate all the insight you have given me. Thanks again
