Normally, when I go off roading or take long road trips, I'll strap two military Scepter fuel cans to the rear section of my roof rack.
I have had zero issues with the cans leaking or getting damaged while being strapped to the roof rack, but I wanted a more efficient way to carry extra fuel.
Some of the issues I had with caring the extra fuel on the roof was weight and how time consuming it was to mount or remove the fuel cans.
This mod that I speak of is Chitown4x4's Powered Rear Window Kit. This kit allows the rear window to be opened or closed (while stationary or moving) using a switch from inside the cab.
We all know how turbulent the air can be inside the FJ with just the front two windows down, but when the rear window is open, the air flow is much more smooth and peaceful.
I feel in love with this kit from the first moment I laid eyes on it. I knew it was only a mater of time before I made it mine and once I had it, I would never let it go.
