Best Jacks to Stabilize TT

ok thanks so much everyone! I expect a little movement but it's feels like more than it should be :)

Try larger blocks under the jacks before you upgrade the jacks. They are more stable as they are cranked down less.

on our 35ft trailer the x chocks and a 3 point stabilizer system helped a great deal. JT stongarms or steadyfast seem to be popular. I have the steadyfast system, and it works great.

However you will NOT eliminate all movement, just reduce it a great deal.

Another vote for the JT Strongarms. Best mod I've ever done. Removed virtually all the movement in my 34' tt.

All trailers have flex in the frame, lightweight trailers have more flex. Pooducts like the Strongarms appear to work great in terms of stiffening up a frame.

Agree ... there's no one solution that's going to eliminate all movement, in fact the only way to completely eliminate movement is to lift the trailer entirely off it's suspension, which is obviously not practical for any non-seasonal trailer. Rotational movement of the wheels can be noticeably reduced with a set of BAL X-Chocks but they're not going to eliminate up / down suspension movement nor that caused by frame flex. With several of the trailers we've owned I've found the combination of a set of X-Chocks to reduce rotational movement and a set of BAL Single Tire Locking Chocks to absolutely prevent the trailer from inadvertently shifting regardless of site slope also works quite well in minimizing suspension movement and I've not had to go any further, such as also using JT Strongarms. However, every trailer is different, some exhibit considerable movement, others not so much, as is one's perception of how much movement is too much and how much is acceptable.

IMO it is NOT NECESSARY as you believe to relieve all the tension on the suspension. You only need to relieve more on the suspension than the weight of the occupants moving around since that is what is flexing the suspension. My experimentation resulted in excellent rock solid stability by providing approximately 400lbs of upward force on both sides of the trailer approx. 6 to 8 ' infront and inback of each axle. The only movement I now have is at the very end of the trailer where I have chosen not to install any supports since that's the bedroom and there is very little moving around in that area and I just live with any movement from that area.

I'm not a believer in any of the support systems that have pivot points in them since that allows some movement and that is exactly what add ons like the JT strongarms, etc. attempt to remove. I simply use 4 screw type jackstands which don't suffer from this piviot joint slop/movement.

First things first, next time your camper is set up somewhere, have the family go inside and walk around. Look at your wheels and tires. I guarantee you that your wheels are rocking back and forth at least slightly as they move. That is a large portion of the movement that you feel. X-chocks or ONEstep or similar products that put opposing pressure on tires to limit rolling will help reduce movement.

All trailers have flex in the frame, lightweight trailers have more flex. Pooducts like the Strongarms appear to work great in terms of stiffening up a frame. Perhaps adding another set of stab jacks in front of and behind the axles would help too. Other than that, you have to learn to live with a little motion in an RV.

We've been quite happy with the ONEstep system, reducing the wheel rotation. That really cut down on the motion that we feel with 2 active kids... now 5 and almost 3.

We also have the Strongarms BUT as I have previously posted unless the rig is on a concrete pad there is still likely to have at least a little movement due to the flex in the ground.
So the ultimate is remove the wheels and use cement blocks or RR ties on a concrete pad.

I have installed the JT Strongarms on 2 5th wheels I’ve owned and they are great! You won’t be disappointed if you install them.

We have a 5th wheel and installed the JT Strong Arms. They have products for both travel trailer and 5th wheel applications. We have been extremely pleased with the results.do some research on prices shopping etc as there is a big flucuation in prices out there.
