Side to side movement when parked

We've begun to spend months in our TT and are wondering how stable it should be. It's a little over 9000 lbs. loaded up, about 37 feet ball to bumper with about a 33 foot box.

I've got the four stabilizers set on blocks of special RR ties, larger than the usual size so they aren't stretched out a lot. I added two adjustable stabilizers, the screw up/down type, under the frame. They aren't real tight but should help a bit.

Sudden movements inside, like the dog jumping off the bed, cause the trailer to move a bit left to right. I pushed the body sideways from the outside at a rear corner and there was a little movement.

None of this is excessive, but maybe it should be more solid. Is all this normal, or is there something I can do to make it more stable?

Would it help to set the A frame on blocks and not rely on the jack when parking for an extended time?
  • For my seasonal TT site, I put flat large patio stone on the ground. I then put 6-ton axle stand on it. 4 x stands down one side of the TT's frame rails. 4 x stands down the other side of the TT's frame rails. If trailer is high off the ground, then use 12-ton axle stands instead (of 6-ton stands). If wondering, axle stands with their wide foot print design on solid patio stone base will dramatically eliminate both front to back and side to side movement. And remember, axle stand isn't made to "lift" the trailer off the ground. They are made to lift some of the chassis weight off its leaf spring suspension and its rubber soft tires.

    Not too sure if above is worth it for traveling trailers. But for seasonal site setup, this works great.
  • Mbutts, yes. I was thinking of either making a set or just buying them.

    And ABC, that's the opposite of what someone told me. Maybe I will try stretching them out as I usually do.

    I think bottle jacks will be more effective than the screw types but I will be careful to not use too much force.

    Is there any way shifting the front jack weight to the A frame directly behind the jack can harm the frame? Should I set the weight on the A frame and immediately shift some weight back to the jack?
  • I've had better luck with the stabilizers when they are closer to fully extended.
  • Have you considered one of the cross bar type of stabilizers?

    BAL is one type.
  • I've found side to side movement is usually in the springs or tires.
    Radial tires being worse.
    Had this problem on my old 5ver after putting radials on.
    Solved it by putting stabalizer jacks just behind the rear wheels to take the weight of the axles.
    You can experiment by using a couple hydraulic jacks to see if that helps before you go to the trouble of installing the stabalizers.
  • The short answer is yes. That will work, but don't put too much pressure on the frame, or you will risk distorting it.
