Stabilizing when at site

We recently bought a 31 foot with a slide and have noticed some considerable bouncing- like on a boat- when people move around. This is our first tt so this is new to us. I do have automatic stabilizers in the front and back but they do not seem to help all that much. Just curious as to what others do. I saw on our last trip that someone had the chocks that were shaped like an "X" in between the tt tires- is this a good method?
Thanks for some insight.

I added scissor jacks to the centre of the trailer and cut a pile of blocks to minimize travel for all six... check out the RV.Net thread.

my TT is pretty small (21 feet ball to bumper, 17 feet inside) and with the 4 corner stabilizers down we dont notice any bounce at all. obviously the size makes a difference, but does a single axle vs 2 axle setup make a big difference too? i noticed everyone mentioning x chocks. i have a single axle, so im guessing this changes the bounce factor as well?

^^^This... Our TT is 37.5 ft long. It came with power stab jacks, I'd rather have manuals though. We were getting a lot of movement so I added X chocks, they added a little stability but adding manual scissor jacks in the center really made a big difference. I plan on welding steel plates to bolt the center jacks to but haven't done it yet.

I was thinking the same thing, but would this still work if you didn't bolt it to the frame? The Harbor Freight jacks mentioned look like they could do the job well.

I tried one thing beyond just putting the stabs down, and it helps considerably. One of the things we noticed was a side-to-side wiggle, where the trailer wiggled around the axles as the pivot point. I made a "redneck" device that is simple. It keeps the tongue from moving at all, which limits the rear of the trailer some, too. I don't use this on overnights with DS, but if DW joins us for a whole weekend or longer, I do use it.

If you try this, just don't make the pea-brained mistake I did the last time I used it. Without thinking, obviously, I started cranking up the tongue to prepare for hitching up to come home. I forgot to remove the chains on this device. It stretched 2 S-hooks beyond usability, so I have to replace those before I use it again. 😮

I use wedges between the tires and upgraded my stabilizers from the cheap factory ones to 7000 lb rated ones. Overkill for my 4500 pound trailer but the wobbling is noticeably reduced.

Since our trailer is raised, the jacks are on tiptoe when they hit the ground -- and that did nothing to stabilize the trailer. And stacks of blocks would wobble. So I made stout wooden tripods to go under the jack pad -- it works well, the tripods come apart for storage, and it is comical:

I find the less I extend the stabilizers the better they work. I either stack yellow blocks under them or I bought a set of light weight aluminum jack stands that I put under each foot....

I would say 90% of the bounce is now gone.



Looks like you just set yours under the frame. I used tec screws and bolted them to the frame in the same manor as the Jayco folks. I had the electric stabilizers on my last 35' TT, I didn't care for them compared to the old scissor jacks.
Oh and I have an aluminum box on the rear bumper that holds 4X6X10" and 2X6X10" blocks to shorten the jacks stroke.

My latest is a 2015 Jayco 40' TT. I had them take my jack off my 35 footer and attach them for me .............. No charge but then that's Jayco here in Michigan
The more you RV the more you find what works and of course what doesn't!


Trailer is at a seasonal site for a couple more months. I'm making brackets and welding them to the top of each jack then clamp the to the crossbar that they are on now which is just in front of the front tires. It's a 2015 that will be going in for some warranty work this fall and I don't want to give any excuse to deny warranty with drilling any holes yet.

I was noticing how much my trailer moved when chocked and the stabilizers tight while camping. I had made a chock like pictured but I used the Harbor Freight wood clamps instead of 4x4 blocks.
I only used the chock when unhooking at my house which is on a little hill just for added security but the last time I went camping I decided to chock the wheel with the wood clamp and WOW what a difference just having one set of tires chocked up tight made with the rocking. I plan on making another chock and doing both sets of tires next time out.


Muddy,
