Valterra Stabilizer Stand

I bought this because our travel trailer moves around a lot, even when my daughter turns over in her bunk bed in the back. We bought two, put one under the rear frame and one under the door on the frame. I really think it took all the motion away. They are relatively inexpensive and easy to set up and take down. Each unit comes with a carrying bag.
The only negative is that it uses the little push in devices that pop up into one of three holes to extend the legs. Both broke on my last trip. I think I can fix it, but when the directions say don't ratchet the straps too tight, they mean it.
There are solutions out there for $400 or more to do the same thing I spent just $100 for. I'm not sure Dyer's is the least expensive, but other sites had it on back order and Dyers delivered in just a few days. Thanks, Dyers!

I've used this item before, unfortunately left it behind one camping trip. Basically, it's an adjustable support you put under the rear bumper of the RV. With the long rear overhang (especially on a Class C), it prevents the rocking motion associated with another person moving through the rig. Setup is simple, and while the rocking isn't completely eliminated, it's greatly reduced. They recommend adding a second one under the entrance door, but I haven't bothered. The only downside; the nylon carrying bag is rather flimsy & will get torn up by the sharp corners of the stabilizer when packing it up. But that's a small price to pay. And Dyers is the cheapest vendor on the market, for this item at least!
