Haven't used them yet and hope I never have to. But when I do, I worry about the proximity of my leveling jack to the relatively loose chain crossing the two tires. Some of these dual chain products pull the chain between two bars. It would calm me down a bit. Of course this is all in my head as I have no real practical experience with it. But I would like to inform you about my observations. In my opinion they are probably suitable for a truck without leveling jacks installed in close proximity to the drive axle tires.
