Lippert makes weld on tabs for the foot pads (if you're referring to the Lippert Level-Up 6 pt system) where you can install the JT Strong arms. We had a 40' rig with the 6 point, and it was all BUT stabilized with our kids running around. King pin stabilizer does not do very much in my opinion. We tried it, but didn't help much with what was going on in the bunk house. Most people I know have created their own version of the JT Strong arms, or diagnal and longitudinal bracing, secured from the jack pads to the frame. It doesn't get much better than that. You can do a google image search for homemade 5th wheel stabilizers and come up with all kinds of stuff. We sold ours when we got out of full timing, but will be doing our own homemade version of the JT's in the near future.
