There are two St. Croix rods in my Jeep at all times. The JKU will hold up to a 7'6" 1 pc rod. All you need are two 12" bungee balls per rod. Wrap one around the roll bar in the back of the vehicle, around the rod and hook it around the ball. Thread the other between the front sound bar and the roof, wrap around the rod (avoiding eyes), and hook the ball.
On road, off road, it doesn't get in the way, there always there, no drilling, no muss no fuss. I also like the little bit of spring for the rods. If you mount two rods, just outside of the center lights, they won't hit you in the head, and won't interfere with the sunvisors.
They work fine for my 2 pc. surf rods too, as well as inshore bass stuff. The most I've hung so far is 6, and it makes it a bit trickier with that many and people in the back seat.
