King Pin Stabelizer

I used to have one and it does help. A bit of a pain to use and sometimes could not use it due to the angle I may be parked on. It does nothing for wiggle in the rear - only the front. I finally sold it and got the SteadyFast stabilizer system and love it. Super eeay to use, you can always use it, nothing under your fifth wheel overhang to be in the way robbing you of space for bikes, etc. Once installed it is always there and usable. It takes about a minute to "deploy". Phillip
