? Chocking to "Stabilize" Question?

Just finished reading some posts reference chocking the wheels to "stabilize" the RV...

Stabilize?

I don't get it - someone please explain.
I see how wedges, x-chocks or whatever hold an RV in position -- you certainly don't want gravity pulling it across an un-level pad. But I don't see how chocks of any kind will help stabilize an RV. Isn't that what the jacks & stabilizers (= somewhat less hefty jacks) are supposed to do? Chocks just hold the wheels in place, the rest of the RV can still rock & roll to its heart's content no matter how tightly the wheels are chocked.
  • I just use the wedge chocks, but I will put a chick behind 2 of the wheels, the back up a bit more, and have the wife and son put the Chocks in front of the wheels, so they really cradle the tires. I can really tell the difference when I do that versus just tapping them into place.
  • I do exactly as wowens79. I chock the back of the rear set of tires (both sides), back up a tad more to add a bit of pressure to those back chocks and set the park brake (if by myself), then chock the front of the front tires.

    The cradling adds enough pressure (if you back up enough) that the suspension doesn't bounce at all and the side to side twisting around that center is eliminated. I do that first then I tighten my side to side DIY frame stabilizers (front and back).


    I learned to do this with my wide spaced axles that x-chock type products don't work well with, and aren't any more effective than the cradling effects.

  • The downside to using wedge style chocks (and in-between chocks such as X-Chocks) is that tires shrink as they cool so even if the chocks are initially quite tight they will loosen noticeably in the first couple of hours. :E That's why I prefer using BAL Standard Tire Locking chocks that can initially be snugged in place, then subsequently be further tightened as the tires cool. :B It's actually shocking how much tires do shrink so the key IMO is to be able to adjust the chocks in fine increments to the smaller tire diameter once the tires are stone cold. Adjusted as such I've noticed there's really not much additional benefit to also installing my X-Chocks so increasingly I'm not bothering with them. Certainly this is about as simple as it gets - park the trailer where you want it, snug up adjustable BAL chocks between each set of tires, then readjust them as the tires cool. Guaranteed, regardless of site slope that trailer isn't going anywhere and it isn't going to rock much either. :B
