I DW dislikes movement immensely. Other than the X-Chocks and snugging my stabilizers, I have 2
Valterra stabilizers; one goes under the rear bumper and one under the frame behind the steps. Even with my LARGE (6'2" & 280+ lbs) son, the movement is fairly negligible. Just the wife and myself, it's pretty darn solid.
BTW, the $35 price on Amazon right now for the Valterras is a great price. I paid in the mid-40's for mine, if not more.
