Kingpin stabilizer

When someone is walking around inside the 5er it will bounce/wiggle. Rubber tires will bounce, suspension systems are made to bounce. To eliminate the bouncing/wiggling you need to keep the weight from pushing down on the tires and suspension by making sure your stabilizers are tight between the 5er and the ground. Don’t just let them out far enough to touch the ground, turn the crank more to make sure they are tight so they will not allow the 5er to push down on the tires. Use a bipod/tripod under the king pin. Make sure it is tight between the ground and the king pin, don’t just adjust it till it touches, tighten it so the front overhang will not move. Make sure to check the stabilizers and bipod/tripod every couple of days because they will loosen up over time. Doesn’t make sense spending a lot of money on landing jack stabilizers when the landing jacks are stable and don’t bounce up and down. If you have properly adjusted the stabilizers and bipod/tripod then you shouldn’t have any bouncing/wiggling. This has worked for me over the past 15 years.
Chocks are to keep the 5er from rolling forward or backwards. They do not eliminate the weight of the 5er from pushing down and causing the bouncing/wiggling. If you park on a site that has a incline/decline then you probably want to use chocks to keep your 5er from rolling when you unhitch.

There are a lot of other options out there to “eliminate” the bouncing/wiggling if you have the extra money and want to spend it.
