travel trailer stabilizer

Thanks much guys. Helpful.

Stabilizing jacks on frame under slide out.........YES

Even bottle jacks on frame

Anything to help firm suspension up will improve the 'no bounce zone'

I installed 2 extra stabilizer jacks on my previous trailer (31 feet long). I tried using all 6 but somehow always had an issue and I finally quit using the 2 middle. The problem was, getting all 6 on the ground with equal pressure. It seems that 1 jack was never snugged up right. When that 6th one was in place, it would cause one of the other 5 to loosen up. After a year of that, I simply quit using all 6.

You can add extra jacks, it won't hurt anything (it might not help anything either. A little trick you may try is to put the new jacks at an angle, rather than square to the frame. And if you add more, add to the main frame of the trailer, not to the slides. The slides need to move with the trailer, like a wing on an airplane. If you tie the "wing" down and the airplane moves, it will break the wing off. A little exaggerated example, but the idea is the same for a trailer with a slide. The slide and the body of the camper should move as one unit. Support the main body and the rest will be OK. Let the "wing" hang free.

One other thing about movement? OK, when was the last time you went shopping for a new house... specifically a new house construction? Ever go to the second floor and have your kids jump up and down at one end of the house, while you are at the other end on the second floor? If not ... you should! You'll be shocked how much the floor shakes under YOUR feet when they jump up and down, not to mention the wall wabbling too!

After that experience, I realized a trailer will never be rock solid unless the wheels come off and the frame is placed on solid concrete.... then? Maybe?

Yes, more scissor jacks will help, but unless you get the weight of the trailer completely off of the suspension, you will always have movement...nature of the beast.

Yes, stabilizers under the slide outs is a no-no.

With my TT I used THESE. I had one under the back of the frame running cross wise, and one under one side running length wise. However, TT still moved somewhat, but much better than without.

Hope this helps

Supports under the slide wont keep the rest of the RV from moving. Also, you really don't want the rest of the V to move while the slide is supported - something will have to give.
Finally, most manufacturers say not to use them.
