My wife and I are blessed that we are not bothered by the slight movement in the trailer when parked. On most overnights I do not bother to even use the rear stabilizers. Sometimes I almost forget to put them down even when we are staying for a few days.
On our first fifth-wheel we were given a tripod. We used it "religiously" for a few trips and then learned that we couldn't tell that it made any difference without it, so it went to the scrap heap.
I know there are many who find it hard to believe how little we are concerned with the slight movements of the trailer, but for us that is just a part of the experience that we are comfortable with.
And for some, it might be worth a try. Otherwise there are good options out there to reduce the movement.
