Question Trailer bounces with jacks down

We have a 2016 27DSRL that came with electric jacks. Even with the jacks down, we can clearly feel the trailer bounce or wiggle with every footstep. That never happened on our previous trailer (which was shorter, and had manual scissor jacks). We bought some additional scissor jacks to put in the middle, but have not permanently attached them yet (still moving them around to see if different placement matters). They help some, but I'm still surprised at how much it bounces with simple footsteps. Is this normal? Any advice?

We have the Lippert self adjusting jacks on our trailer, I assume that you have the same. They were the biggest disappointment and waste of money we have had in a long time. In order to self adjust side to side, a carriage must slide back and forth under the trailer. Even though the jacks are down and tight, the trailer rocks on the carriage. I can't imagine a worse design. The style with a motor for each jack is much better. We purchased a set of very heavy duty manual scissor jacks and place them just ahead of the axles. Much reduced bounce. We have not permanently attached them, I slide them in place using these brackets, and store the jacks in the pass through.https://www.amazon.com/Mounting-Brac.../dp/B005ZI03GS

The longer the trailer the more the bounce will be felt.

X-chocks between the wheels will help, adding another stabilizer jack right in front of the wheels will also help. There are a few more options too.

We ordered the stabilizer option with our TT, big mistake... they never came close to stabilizing the TT. Went to Harbor Freight and picked up 4 heavy duty scissors jacks.. moved them around the frame until I found the best locations for them. I then lowered the stabilizers and they keep the ends of the TT from bouncing. The frame is so long and the middle sits on the wheels/suspension, so it is free to flex.. not any more!!!

Problem is not unique to Jayco

Your complaint is seen on many forums. It is annoying and you can find suggestions to help but I don't think you will ever find a 100% cure for the bouncing. If you do please let us all know!

We went LONG with our newest camper and I am feeling your pain. I can tell when one of my kids rolls over in their bunk!! We added jacks under our slides (2 for each slide) (along with x-chock between wheels) and that has helped dramatically. Good luck!

Cement blocks.... Evenly spaced under the frame. Lol About the only thing that would eliminate 100% of the bouncing. Somewhat impractical though.

Steve & Nancy,

As mentioned, the practical solution is another set of scissor jacks just in front of the front tires. And possibly X-chocks.

Good luck!

Here are a couple photos of my experimenting with jacks right in front and back of the axles. These are the Camco screw type jacks that are about $20 per pair.

I found that 1 jack on either side right behind the axle took away about 95% of the sway and bouncing, so that's what we do now.

Only put on enough pressure to prevent being able to move the jacks laterally. We aren't lifting the trailer here.

Here is a link to the scissor jacks I purchased. They are the sturdiest ones I could find.
