Hi Rob, we tried using a king pin stabilizer for a short time. It only did a small change in the rocking of the 5th wheel. Also setting up/ tearing down was a pain, and finding the area to store it wile we were in transit.
Rob We use the stabilizers and also had some locks for the wheels made(to keep the springs from flexing). When our trailer was made the brackets on the frame were installed so I had the arms made at a welding shop. At times we use king pin stabilizer if wind is bad.
I have a stabilizer that my dad used back in the day. Looks like something that Columbus might have brought over with him. I use it account it does a good job taking the wiggle out of the front end. We will probaly go to the ones Eddie mention when we get out west near them next Jan.
Rob I installed Steadyfast stabilizer on my previous 5er worked great , they are similar to JT strong arm stabilizers. Either one will work good for you. The reason I went with the Steadyfast they where easier to use.
I’ve not use a king pin stabilizer but I’ve got the Steady fast and can’t say enough good about it. Excellent construction, made in the US and took out about 90% of our bounce out of our lightweight 5ver. Best add-on I’ve done on my rig.
