Mag mount Cb antenna route 2023 double cab

Drivers side rear in line with rocker panel does this access the cab at all

 

Not in that picture..

 

I believe there is a vent under the sliding window. You might be able to video with your phone taped to cardboard between the cab and the bed. I don't know the answer.

 

There are vents right in that crevasse that go inside to the cab. The pressure vents I believe. If you pull down the rear seats you can check for them.

 

There are two air release vents, one on each side, just below the rear window, and behind the rear seats.
Probably not an idea place to be running coax, but to each their own.
