I will look into the door bar. Yes one latches to the other. I cut the ends of each bar at an angle so they secured to each other but it doesn't work as well as I thought LOL. I would like to latch it to the bumper for better security but the way the tailgate swings down there isn't much room between the bumper and the tailgate.Looks good, except the latch. Do you just have one side latching to the other?
In that situation, i would use what is called a door bar connector for roll cages in race cars. I dont see the current latch holding up to much offroad abuse.
