Camper rocks

We have a 2011 Flagstaff 831 FLSS that has electric stabilization jacks. When using these jacks the camper rocks and sways when there is any movement in the camper eg. entering/exiting the camper. Any suggestions on how to eliminate this would be most appreciated. I forgot to mention it has 2 slide outs. Thanks

Not sure what the power source of the jacks has to do with trailer movement, but I do notice a lot of movement in the RV when anyone is walking around or going up/down the stairs. I suspect that the fact that these trailers are long and flexible, and they are on wheels with suspensions we will get movement. The only way to eliminate the movement would be to support the frame at several spots (th more the merrier) along the length.

I have read that a number of people on here recommend "BAL X-Chock's" or they make their own version. Do a search for them. Also, They have "RV step supports" that keep your trailer from shifting when getting in an out. I plan on getting both very soon.

Scissors jacks under the frame and a step support work wonders! Takes almost all of the movement away. make sure you're putting wheel chocks between your wheels and cinch them tight.

Use the stabilizer jacks, plus add X-Chocks between the tires. Under the suspension or the frame, use a bottle jack, scissor jack or something to take the spring movement away.

Under the frame. A jack under the spring hanger works great also

It has been my experience that a TT/5er can move in several ways. Different steps are needed to stop a specific movement.

Bounce is caused by the camper suspension (springs and pneumatic tires) flexing when someone is moving (walking) in the camper. I have found that a jack between the tires, on the suspension frame and just snugged up, helps a lot with bounce.

Side-to-side movement. I had this a lot in my 5th wheel. JT strong arms, home made cross support or like products on the landing gear and support rear jacks help stop most if not all of this.

Roll or front to back movement is caused by the running gear not being locked where the wheels can not move. X-chocks or the like between the tires along with wheel chocks in front of and behind the wheels will help with this movement.

Rocking, different from the side-to-side movement. I did not have this until I got my latest TT. Like yours we have two large slides on the left/back side of the TT. For this I use two slide-out supports under my biggest slide, snugged up to a 2x4 against the slide floor bottom without lifting the slide. And one support under the entry steps. There are a lot of naysayers on RV forums about slide-out supports. Most of the warnings are if you have a flat, the supports don't move and I would have excess pressure on the slides. However with the two jacks between the tires I feel this "warning" is nullified. Also I wrote the Rockwood Rep. and asked him about support slides. His reply was the the underside could handle it without a problem. I can provide a copy of the email if anyone would like to read it.

My 2 cents

I have BAL X- chocks - got them even before I got the tailer. They are designed to keep the trailer from rolling away. They do nothing for trailer shaking which is mostly a vertical perturbation.

Russ' post above is right on the money.

I have decided to live with my motions. Can't be bothered with all these supports unless full timing and stationary.

Hmmm, I apologize for the misinformation then. I know their primary purpose is to be a tire chock, to keep the unit from rolling away Although, It seems like at least a few people on here have recommended them for improving overalll stability as does the BAL website. I never used them tho so.....i'll shut up now.

BAL - Innovative Products for the RV Industry

I've seen this discussed before, and according to their own website, they're advertised for *stabilizing*. So, Bryan, according to them, you're correct.

That video mentions nothing about preventing roll away, though common sense dictates that this would *help* to prevent that. The video also shows how applying that device minimizes movement of the trailer.

DH and I definitely use the X chocks, but we don't depend on them to keep the RV "in place"...we use additional chocking devices for that.

We also use the small adjustable pedestals under the bottom step at both doors to prevent the side to side rocking when entering or exiting.

Edit to add: during the trip we just arrived home from, our camp neighbor reminded us that when you apply the X chocks when setting up, wait a few hours and tighten them again as the tires cool down...might have to do it a couple of times.

This video addresses that issue as well.

With every trip we learn something new, sometimes more than one thing...see our thread about "furnace smoke".
